Ukadaulo wa maofesi (i)

September 04, 2023

Masamba owonda amatchedwanso makhadi akunja. Magetsi, mazira, ndipo mapepala a disc adapangidwa pambuyo pa pulasitiki wa thermoplastic amatenthedwa ndikupangidwa kuti amawoneka bwino, ndipo mawonekedwe a malonda akhoza kuwoneka bwino. Nthawi yomweyo, khadi ngati gawo lapansi limatha kusindikizidwa ndi zojambula zokopa komanso malangizo ogwiritsira ntchito malonda, otsogolera. ndi kugwiritsa ntchito. Kumbali inayi , katundu wonyamula katundu amakhazikika pakati pa chithuthu ndi gawo lapansi, ndipo sakuwonongeka mosavuta panthawi yoyendera ndi kugulitsa, kuti zinthu zina zizitetezedwa ndi zinthu zina. Kuteteza katundu kwa nthawi yayitali kungathandizenso kupititsa patsogolo kugulitsa katundu. Thermoplastic yolowera kunja kwa 1970s idagwiritsidwa ntchito makamaka ponyamula mapiritsi, makapisozi, suppositories, chifukwa cha kuchuluka kwa njira za zakudya komanso zofunikira tsiku lililonse. Pakadali pano, malo osungira mafuta amagwiritsidwa ntchito makamaka pakupanga mankhwala opangira mankhwala, chakudya, zodzoladzola, ma stativery, zida zamagetsi ndi zigawo, mphatso, zokongoletsera ndi zina zokongoletsera ndi zina.
Maphukusi a moromofod amaphatikiza mapaketi ndi mapaketi amthupi. Ngakhale kuti ndi amtundu womwewo wa njira yofananira, pali kusiyana kambiri pa mfundo ndi ntchito.
Chizindikiro cha Black Tsickiglogy Njira iyi idayamba kupanga ndikulimbikitsidwa ku Germany kumapeto kwa zaka za m'ma 1950. Choyambirira kugwiritsidwa ntchito poyendetsa mapiritsi ndi makapisozi. Zinali kusintha zosokoneza za mapiritsi monga mabotolo agalasi ndi mabotolo apulasitiki, komanso ndalama zomwe zimapangidwira mizere yopanga zinali zazikulu. Zoyipa, kuphatikiza ndi chitukuko cha mapangidwe a mlingo, kufunikira kwa mapiritsi ang'onoang'ono a mapiritsi akuwonjezeka. Piritsi lodzaza ndi chitholiro likafinya kuwira pang'ono ndi dzanja, piritsi limatha kutuluka mu zojambulazo za aluminium, ndipo nthawi zina zimatchedwa kuti zidasungunuka kapena kujambulidwa.
Phukusili lili ndi kulemera kopepuka, mayendedwe abwino; Kuchita masewera olimbitsa thupi, kumatha kupewa chinyezi, fumbi, kuwonongeka, kuba ndi kuwonongeka; imatha kugwiritsa ntchito zinthu zilizonse zowoneka bwino; Kulongedza sikugwiritsa ntchito zinthu zina zokongola komanso mawonekedwe osavuta, osavuta kugulitsa ndi zowonjezera zowonjezera, pali zothandiza monga kuti matebulo atseke sangasakanizidwe ndipo sadzawonongedwa. Chifukwa chake, mtundu wamtunduwu wapangidwa mwachangu.
Choyamba, zofananira zachilengedwe chifukwa cha kukula kwa chithupu, pali mitundu yambiri pamsika, monga momwe chithunzi:
a. Tsamba losindikizidwa mwachindunji.
b. Gawoli limayikidwa mu slot yapadera.
c. Kukakamiza kumabzala chithumwa.
d. The bubble imasindikizidwa pa gawo lapansi lokongoletsedwa.
e. Pambuyo pa chithuthu kapena thireyi limayikidwa mu gawo lotsekedwa, limasindikizidwa.
f. Gawoli lili ndi pepala lophimba lomwe limatha kutsekedwa.
g. Hafu ya gawo lapansi ndi lofota, kulola malonda kuyimirira pa alumali.
h. Kufikira kwaulere kwa malonda osatsegula matuza.
i. Chikwama cha mbali ziwiri, chopindika.
J. Pulasitiki yonse yopanda msewu wapansi.
k. Phukusi lodzaza kawiri.
l. Kulekanitsa mapaketi angapo.

m. Mapulasitiki onse apulasitiki kapena awiri osambira popanda miyala yamiyala.

Chachiwiri, kusankha kwa zida za bulangeti kuchokera ku dispages paketing, kumapangidwa makamaka ndi pulasitiki ya thermoplastic ndi gawo lapansi, ndipo ena amagwiritsanso ntchito zidutswa zomata kapena zina zothandizira.
1. Pali mitundu yambiri ya mapepala apulasitiki omwe angagwiritsidwe ntchito mu matumba a chithupsa a pulasitiki. Iliyonse mwa mitundu yapulasitiki iyi, kuwonjezera pazinthu zonse zomwe zimachitika zokhazokha, monga kuthira, monga makulidwe chifukwa cha kusamvana ndi zowonjezera zomwe zimagwiritsidwa ntchito. , mphamvu, mphamvu, kupatuka kopepuka, chinyezi, kukalamba, kutentha, kutentha, kutentha, kosavuta kudula ndi zina zotero. Nthawi yomweyo, kukula kwake, kuchuluka kwa kulemera ndi kukana kwa malembawo ndi mawonekedwe a malembawo, monga kupezeka kwa madokotala akuthwa. Chifukwa chake, mapepala apulasitiki amayenera kuganiziridwa mukamasankha zida za blister. Ndipo kusinthasintha kwa zinthu zoyikidwa, ndiko kuti, kusankha kwa zida kukwaniritsa zofunikira za chithumba, pomwe mukuchepetsa mtengo.
Mwambiri, pali mitundu itatu ya mapepala olimba a pulasitiki otchinga: cellulose, snyeene, ndi vinyl. Pakati pawo, cellulose amagwiritsidwa ntchito kwambiri, kuphatikizapo ma cellulose acetate cellulose, cellulose komalute, ndi cellulose. Onsewa amakhala ndi kuwonekera kwambiri komanso kuwonekera bwino kwambiri, kutentha bwino panyanja ndi kukana mafuta ndi mafuta. Komabe, kutentha kusindikiza chinyontho kwa cellulose nthawi zambiri kumakhala kokulirapo kuposa mapepala ena apulasitiki. Oukirana monyada amakhala ndi mawonekedwe abwino kwambiri, koma alibe mphamvu zotsutsana ndipo umasweka mosavuta. Pa kutentha pang'ono, kumawonekera kwambiri, koma kumakhala ndi njira zopirira. Vinyl imayendera nthawi zambiri yotsika mtengo kuposa styrene, ndipo ndi olimba komanso ofewa. Itha kukhala yosindikizidwa kutentha ndi pepala lokutidwa. Kuwonekera kumakhudzidwa ndi zowonjezera. Ena ndi abwino ndipo ena ndi abwino kwambiri. Kuonjezera pulasitiki kumatha kusintha kuzizira komanso kulimbitsa mphamvu. Palinso mapepala apulasitiki monga polyvinyl chloride / Polyvinyl chloride / Polychlorotride, polyvinyl chloride chloride kudikirira. Mukamapanga zinthu zomwe zimafuna mpweya wambiri wotchinga ndi kuwala, mapepala apulasitiki ndi buku la aluminium cormiset Zipangizo ziyenera kugwiritsidwa ntchito; Zakudya ndi mapiritsi, zosewerera pulasitiki ziyenera kugwiritsidwa ntchito.
2. Gawo lopindika ndi gawo lalikulu la phukusi la chithuthu. Monga filimu yapulasitiki, kukula kwake, mawonekedwe ndi kulemera kwa chinthu chonyamula iyenera kuganiziridwa posankha gawo lapansi.
Mitengo imakhala makamaka katoni woyera, mtundu wa B-mtundu wophimba (mwachidule) pepala lophimba (makamaka chisindikizo) Pepala loyera limapangidwa kuchokera ku blyp ya sulfite. Ndizothandizanso papepala ndi mapepala atsopano a NewsProte papepala. Pamwamba pa pepala lalikulu liyenera kukhala loyera komanso zosindikiza zabwino, zitha kuyikanso chisindikizo chenicheni, ndipo tiyeneranso kukhala ndi mphamvu yomanga misozi itatha atasindikizidwa ndi chithuza. Makulidwe a pepala loyera loyera limachokera ku 0.35 mpaka 0.75 mm; Wogwiritsidwa ntchito wamba ndi 0,45 mpaka 0.60 mm.
Chachitatu, kusankha kwa njira yowonera yofiyira kufiyira, bokosi la disving, lokhala ndi ma disk, ndi zina zosiyana, mawonekedwe amasiyanasiyana malinga ndi zinthu za oyikidwa; Gawo lothandiza, palibe magawo magawo. Nthawi yomweyo, chifukwa cha kusiyanasiyana kwa gawo la mawonekedwe, gawo la kutentha, ndi gawo la kutentha kwa makina ogulitsa, mitundu ya makina ophatikizika ndi ambiri, koma titha kugawa Black amanyamula mu ntchito zamakina ndi makina malinga ndi momwe amagwirira ntchito. Gwiritsani Ntchito Magulu Awiri Akuluakulu.
1. Njira iyi kuntchito yamanja ndiyoyenera kupanga mitundu yambiri ndi mabatani ang'onoang'ono m'malo osakwanira ndalama zokwanira komanso ntchito zokwanira. Chitsamba ndi gawo lapansi ndizopangidwa kale, zosindikizidwa ndikukhomedwa, ndipo chinthucho chimayikidwa mu chithuza, chophimbidwa ndi gawo lapansi, kenako linasindikizidwa pamoto wowiritsa. Zinthu zina sizikhala ndi chidwi ndi chinyezi komanso kuwuma ndipo zitha kusunthidwa mwachindunji ndi stapler.
2. Makina Ogwiritsa Ntchito Okhawo Ngakhale pali mitundu yambiri ya makina a Paketi, mfundo zawo zopangidwa nthawi zambiri zimakhala zofanana. Makina okonda kwambiri amasunga masamba a madontho opangira madontho, malo otenthetsera, masamba owumba, masamba odzaza, masamba omaliza, ndi malo opindika. Kutulutsa kwa chidebe chowumbidwa ndi gawo lomwe zinthu zowonjezera zimasonkhanitsidwa zimawonetsedwa mu Chithunzi 11-2.
.
. Kenako, nkhungu imadzazidwa ndi mpweya wothinikizidwa kuchokera pamwamba kuti mulumikizane ndi khoma ku khoma la nkhungu kuti apange chithuthu kapena chikho. Ngati matuza kapena mapiritsi sakhala akuya ndipo filimuyo ndi yochepa thupi, vacuum imakokedwa pansi pa nkhungu kuti apange filimu ya pulasitiki.
.
(d) Kutentha kumangirira kuzungulira miyala ndi chithuza.
(e) Kumatula mu chinthu chimodzi chomaliza. Kuphatikiza pa ntchito pamwambapa, mzere wopangidwa kwathunthu wopangidwa umaphatikizidwanso ndikuwunikiranso zida zochotsa, zida zosindikiza, ndi malangizo amsonkhano, momwe zimakhalira. Kugwiritsa ntchito makina mokwanira ndi koyenera kupanga mitundu imodzi, osati zokolola zambiri zokha, mtengo wotsika mtengo, komanso umakumana ndi zofuna zaukhondo komanso zinthu zazing'ono zomwe zimagwiritsidwa ntchito kwambiri ponyamula.
