Ntchito zazikulu za PVC.

1. Mbiri za PVC

Ma profiles ndi ma profiles a PVC ndi madera akuluakulu omwe PVC imagwiritsidwa ntchito kwambiri ku China, zomwe zimapangitsa kuti pakhale pafupifupi 25% ya ndalama zonse zomwe PVC imagwiritsidwa ntchito. Amagwiritsidwa ntchito kwambiri popanga zitseko ndi mawindo ndi zipangizo zosungira mphamvu, ndipo kuchuluka kwa ntchito zawo kukukulirakulirabe mdziko lonse. M'maiko otukuka, msika wa zitseko ndi mawindo apulasitiki uli pamwamba, monga 50% ku Germany, 56% ku France, ndi 45% ku United States.

2. Chitoliro cha PVC

Pakati pa zinthu zambiri za PVC, mapaipi a PVC ndi malo achiwiri omwe amagwiritsidwa ntchito kwambiri, omwe amapanga pafupifupi 20% ya zomwe amagwiritsidwa ntchito. Ku China, mapaipi a PVC amapangidwa kale kuposa mapaipi a PE ndi mapaipi a PP, okhala ndi mitundu yambiri, magwiridwe antchito abwino komanso mitundu yosiyanasiyana yogwiritsira ntchito, zomwe zimakhala ndi malo ofunikira pamsika.

3. Filimu ya PVC

Kugwiritsa ntchito PVC m'munda wa filimu ya PVC kuli pachitatu, pafupifupi 10%. Mukasakaniza ndi kuyika PVC mu pulasitiki ndi zowonjezera, gwiritsani ntchito kalendala ya mizere itatu kapena inayi kuti mupange filimu yowonekera kapena yamitundu yokhala ndi makulidwe enaake, ndikukonza filimuyo mwanjira iyi kuti ikhale filimu yozungulira. Matumba olongedza, ma coat a mvula, nsalu za patebulo, makatani, zoseweretsa zopumira, ndi zina zotero zitha kukonzedwanso podula ndikutseka kutentha. Filimu yowonekera bwino ingagwiritsidwe ntchito pa greenhouse, greenhouse ya pulasitiki ndi filimu ya pulasitiki. Filimu yotambasulidwa mozungulira ingagwiritsidwe ntchito polongedza chifukwa cha kutentha kwake.

4. PVC zinthu zolimba ndi bolodi

Onjezani zokhazikika, mafuta odzola ndi zodzaza ku PVC, ndipo mutatha kusakaniza, gwiritsani ntchito chotulutsira kuti mutulutse mapaipi olimba, mapaipi opangidwa mwapadera, ndi mapaipi okhala ndi ma corrugated a mainchesi osiyanasiyana, omwe angagwiritsidwe ntchito ngati mapaipi a zimbudzi, mapaipi amadzi akumwa, zitseko za waya kapena zogwirira masitepe. Mapepala okhala ndi kalendala amaikidwa pamwamba ndikuponderezedwa kuti apange mbale zolimba za makulidwe osiyanasiyana. Mapepalawo amatha kudulidwa m'mawonekedwe omwe mukufuna, kenako amalumikizidwa ndi mpweya wotentha pogwiritsa ntchito ndodo zolumikizira za PVC kuti apange matanki osiyanasiyana osungiramo zinthu osagwiritsa ntchito mankhwala, ma ducts a mpweya ndi zotengera.

5. PVC zofewa zonse

Zipangizo zotulutsira zingagwiritsidwe ntchito kutulutsa mapayipi, zingwe, mawaya, ndi zina zotero; makina opangira jakisoni angagwiritsidwe ntchito kufananiza nkhungu zosiyanasiyana popanga nsapato zapulasitiki, zidendene, masilipi, zoseweretsa, zida zamagalimoto, ndi zina zotero.

6. Zinthu zopangira PVC

Zinthu zopangidwa ndi PVC zimagwiritsidwa ntchito kwambiri m'mabotolo osiyanasiyana, mafilimu ndi mapepala olimba oti azilongedza. Mabotolo a PVC amagwiritsidwa ntchito kwambiri popanga madzi amchere, zakumwa, ndi mabotolo odzola, komanso amagwiritsidwa ntchito polongedza mafuta oyeretsedwa. Filimu ya PVC ingagwiritsidwe ntchito pophatikizana ndi ma polima ena kuti apange ma laminates otsika mtengo, komanso zinthu zowonekera bwino zomwe zimakhala ndi zotchinga zabwino. Filimu ya PVC imagwiritsidwanso ntchito pokulunga matiresi, nsalu, zoseweretsa ndi zinthu zamafakitale.

7. PVC siding ndi pansi

Ma PVC siding amagwiritsidwa ntchito kwambiri m'malo mwa aluminiyamu siding. Kupatula gawo la polyvinyl chloride resin, zigawo zina za matailosi a pansi a polyvinyl chloride ndi zinthu zobwezerezedwanso, zomatira, zodzaza ndi zigawo zina, zomwe zimagwiritsidwa ntchito kwambiri pansi pa nyumba zoyimilira ndege komanso nthaka yolimba m'malo ena.

8. Zinthu zogwiritsidwa ntchito ndi polyvinyl chloride

Chikwama cha katundu ndi chinthu chachikhalidwe chopangidwa ndi polyvinyl chloride. Polyvinyl chloride imagwiritsidwa ntchito popanga zikopa zosiyanasiyana zongopeka za matumba a katundu ndi zinthu zamasewera monga basketball, mpira wamiyendo ndi rugby. Ingagwiritsidwenso ntchito popanga malamba a yunifolomu ndi zida zapadera zodzitetezera. Nsalu za polyvinyl chloride za zovala nthawi zambiri zimakhala nsalu zoyamwa (palibe chophimba chofunikira), monga ma capes amvula, mathalauza a ana, ma jekete achikopa ongopeka ndi nsapato zosiyanasiyana zamvula. PVC imagwiritsidwa ntchito pazinthu zambiri zamasewera ndi zosangalatsa, monga zoseweretsa, zolemba ndi zinthu zamasewera. Zoseweretsa za PVC ndi zinthu zamasewera zimakhala ndi kukula kwakukulu, ndipo zili ndi ubwino chifukwa cha mtengo wotsika wopanga komanso kupangika kosavuta.

9. Zinthu zopangidwa ndi PVC

Chikopa chopangidwa ndi kumbuyo chimapangidwa poika phala la PVC pa nsalu kapena pepala, kenako nkulipaka pulasitiki pamwamba pa 100°C. Chingapangidwenso poyika PVC ndi zowonjezera mu filimu poyamba, kenako nkuzikanikiza ndi substrate. Chikopa chopangidwa popanda kumbuyo chimayikidwa mwachindunji mu pepala lofewa la makulidwe enaake ndi kalendala, kenako nkuzikanikiza ndi chitsanzo. Chikopa chopangidwa chingagwiritsidwe ntchito kupanga masutukesi, zikwama, zophimba mabuku, masofa ndi ma cushion a magalimoto, komanso chikopa cha pansi, chomwe chimagwiritsidwa ntchito ngati zipangizo zapansi pa nyumba.

10. Zinthu zopangidwa ndi thovu la PVC

PVC yofewa ikaphwanyidwa, kuchuluka koyenera kwa thovu kumawonjezedwa kuti apange pepala, lomwe limaphwanyidwa thovu ndikupanga pulasitiki ya thovu, yomwe ingagwiritsidwe ntchito ngati zotchingira thovu, nsapato, zophimba nkhope, ndi zinthu zomangira zoteteza ku shockproof. Ingagwiritsidwenso ntchito kupanga mapepala olimba a PVC otsika thovu ndi zinthu zophimbidwa ndi profiled kutengera zotulutsira, zomwe zingagwiritsidwe ntchito m'malo mwa matabwa. Ndi mtundu watsopano wa zipangizo zomangira.

11. PVC mandala pepala

Onjezani chosinthira mphamvu ndi chokhazikika cha organotin ku PVC, ndipo chikhale pepala lowonekera bwino mutasakaniza, kuyika pulasitiki ndi kuyika kalendala. Chingapangidwe kukhala ziwiya zowonekera bwino zokhala ndi makoma ochepa kapena kugwiritsidwa ntchito mu phukusi la vacuum blister pogwiritsa ntchito thermoforming. Ndi chinthu chabwino kwambiri cholongedza komanso chokongoletsera.

12. Zina

Zitseko ndi mawindo zimasonkhanitsidwa ndi zinthu zolimba. M'mayiko ena, msika wa zitseko ndi mawindo wakhala ukugulitsidwa pamodzi ndi zitseko ndi mawindo amatabwa, mawindo a aluminiyamu, ndi zina zotero; zipangizo zamatabwa zongopeka, zipangizo zomangira zomwe zimalowa m'malo mwa chitsulo (kumpoto, m'mphepete mwa nyanja); zotengera zopanda kanthu.
