Kodi vanium brister ndi chiyani?

Njira yopanga vacuum idadziwikanso kumayambiriro kwa zaka za zana la 20, koma kugwiritsa ntchito kwake ku mafakitale kunali kokha, koma kunali kokha

anapangidwa mu 1960s. Zaka 20 zapitazi, zakhala zikupanga njira imodzi yofunika kwambiri yopangira zida za Pacy. Kukula kwaukadaulo kwaukadaulo kumeneku kumachitika chifukwa cha kusinthasintha kosalekeza kwa njira ndi zida, komanso chitukuko cha ma sheet atsopano omwe amapanga katundu; Imatsimikiziridwanso ndi kukula kwa makampani ogulitsa ndi mawonekedwe a kutchutsidwa.

Kupanga vacuum ndi imodzi mwa njira zofananira kwambiri zonyamula zotengera zapulasitiki. Umaukadaulo wowonjezera womwe umagwiritsa ntchito mapepala a thermoplastic ngati chinthu chowumba. M'mayiko akunja, mawonekedwe a racuum ndi njira yakale youmba. Chifukwa cha kuchuluka kupititsa patsogolo, kwakhala kokhazikitsidwa kwambiri ndikupangidwira, ndipo sikukwaniritsa zinyalala, ndipo 100% yaiwisi ndi zopangira zosafunikira zakhala zopangidwa. Kupanga ukadaulo wa dongosolo kuti azipanga mzere wonse. Chikopa chachitsulo  

Vuto la Vacuum limasiyana m'njira zotsatirazi:

Kutentha kwawonso kumafunikira kuti mutenthe zinthu zomwe zimapangika

Zojambulazo nkhungu zomwe zimagwiritsidwa ntchito popanga pulasitiki

CO · COZONGA CHOKHUDZA KUCHEMBEDWA KWAMBIRI Komwe Sizisintha Kukula

Chigawocho chija chikakhala chiwonetsero chikakhala chokhazikika

Nthawi zambiri, kutumiza mankhwalawa kuthyoka ndikofunikira, monga:

Kutentha, kuwotcha, kuyala, kuluma, kutentha, kukuka, kukumbutsa, kusindikiza, kusindikiza

Kukhazikika kwa vacuum tsopano kumakhala nthawi yovomerezeka pankhani yokonzanso: "Chingeni". Ndi "Kukakamizidwa" kumatanthauza njira zapadera zomwe zimagwiritsa ntchito kuthamanga kwa mpweya. "Kutentha" ndi mawu ambiri owumbira osiyanasiyana a thermoplastic, kuphatikiza ndi kukakamizidwa, kapena kuumba.

Choyamba, maubwino ndi zovuta za pulasitiki ya vacuum

Kuweruza ngati njira iliyonse yosinthira ndi kupanga ndizopambana, kaya mtengo wa zinthu zopangidwa ndi njirayi ndi koyenera poyerekeza ndi njira ina yokonza; Kapena mtengo wa zinthu zopangidwa ndi njira ziwiri ndizofanana, koma kugwiritsa ntchito njirayi mtundu womwe umapangidwa umapangidwa ukuyenda bwino. Pa ntchito zambiri, jakisoni akuumba kapena kuwombera Kupanga mpikisano ndi vacuum kupanga.

Koma malinga ndi ukadaulo wa ma CD, kusinthasintha kwa kusintha kwina sikunakhalepo njira zina zothandizira kupikisana naye pokhapokha mutapangidwa ndi makatoni. Ubwino waukulu wa kusintha kwa vacuum ndi chuma chake chakunja. Tsamba lophatikizidwa, pepala lokota, ndipo pepala losindikizidwa limapangidwa m'malo mwa makina osintha omwe ali ndi kusintha koyenera. Zolemba zocheperako zitha kukhala vacuum yopangidwa kuchokera ku ma sheet osungunuka, pomwe ma pellets ndi khoma lomwelo limafuna kuti asungunuke otsika. Kwa magawo apulasitiki ochepa, mtengo wowuma ndi mwayi wina wa vacuum kupanga, komanso magawo ambiri, ndizopindulitsa kwambiri kukwaniritsa khoma lopyapyala ndi kuchuluka kwa makina opanga. .

Gawo laling'ono lomwe lingapangidwe ndi vacuum kupanga ndi phukusi la piritsi kapena batri la wotchi. Zimathanso kutulutsa zinthu zambiri, monga dziwe la 3 mpaka 5 mpaka lalitali. Kukula kwa zinthu zakuumba kumatha kuchokera pa 0,05 mpaka 15 mm, ndipo kwa zinthu zopukutira, makulidwe amatha kukhala mpaka 60 mm. Zinthu zilizonse zapansi kapena zofananira zitha kukhala za vacuum zopangidwa.

Zinthu zomwe zimagwiritsidwa ntchito popanga vacuum ndi pepala kukhala ndi makulidwe a 0,05 mpaka 15 mm, ndipo ma sheet awa ndi zinthu zomaliza zopezeka pogwiritsa ntchito ma pellets kapena ufa. Chifukwa chake, sinthani zinthu zopangira zowonjezera zimawonjezera ndalama zowonjezera poyerekeza ndi jekeseni.

Tsambalo likufunika kudulidwa nthawi ya vacuum kupanga, lomwe lidzabala scrap. Izi zopukutira zimakhazikika ndikusakanizidwa ndi zinthu zoyambirira kupanga pepala kachiwiri.

M'pulogalamu yopanga, malo amodzi okha a pepalalo akukhudzana ndi nkhungu yopanga, kotero kuti malo amodzi okha agwirizane ndi geometry ya geruum yopanga nkhungu.

Mu gawo la procespukiki yapulasitiki, mawonekedwe a racuum amadziwika kuti ndi njira yosinthira ndi kuthekera kwakukulu. Amapangidwa komanso oyenera kudera lonse la pulasitiki. Kupanga vacuum kulinso njira yosinthira yomwe imafuna ntchito yaluso komanso luso lanu. Masiku ano, kuwumba vacuum kumachitika m'njira yolamulira mwamwano ndikusintha njira komanso ukadaulo wofunikira.

M'zaka zaposachedwa, kubwezeretsanso kwa scrap komwe kumapangidwa panthawi yomwe tchuthi chakhala kofunika kwambiri. Masiku ano, njira yapangidwa pomwe scrap imabwezedwanso ndikusakanikirana ndi zinthu zoyambirira. Zogulitsa pulasitiki, monga zida zapamapaketi, komanso zigawo zama injini, zitha kubwezeretsedwanso pansi pamakhalidwe ambiri, koma ena amafunikirabe. Zinthu zomwe zikuwoneka bwino ndizomwe zimapangidwa makamaka zida ndi zida zamagetsi. Kuti tisinthe pokonzanso, tiyenera kugwira ntchito molimbika pa zachilengedwe ndi zachuma zamakono.

Zogulitsa zamitundu ya vacuum ili ndi zabwino za mtengo wotsika, kuchita bwino kwambiri, kusankha kwaulere, zoseweretsa zamagetsi, zamagetsi, chakudya chamagetsi, chakudya chomwe chimasungidwa Zodzikongoletsera ndi zinthu zina zakonzedwa kuti zigwiritsidwe ntchito maasiketi, magalimoto, magawo opangira mafakitale, zikopa, mabokosi ogulitsa ndi mabokosi aulimi.

Kuumba kwachiwiri, vacuum pulasitiki kumakhala ndi malire ake

Kupanga kwapulasitiki yapulasitiki kumangopanga zinthu zosavuta theka ndi kapangidwe kake ka zinthuzo kuyenera kukhala yunifolomu.

Kuyaka kwa vacuum kupanga zinthu ndi zochepa. Mwambiri, kuya kwa diamer ramer (h / d) za chidebe sichidutsa chimodzi.

Kusa kulondola kwa ziwalozo ndi osauka, ndipo cholakwika chaching'ono chimakhala pamwamba 1%. Sizovuta kupeza kusasinthasintha kwa makonzedwe kapena kukula kwa magawo osiyanasiyana popanga, ndipo kufanana kwa khoma la mbali imodzi ndi kovuta kutsimikizira. Kuphatikiza apo, zina zambiri za nkhungu panthawi yopanga kusinthana kumakhala kovuta. Siziwoneka bwino mu malonda.
