PVC ikusintha zida zomangira monga matabwa, zitsulo, konkriti ndi dongo pazogwiritsa ntchito zambiri.
Kugwiritsa ntchito mosiyanasiyana komanso kugwira ntchito bwino kwambiri kutanthauza kuti ndi njira yofunika kwambiri yomanga gawo, lomwe limawerengedwa kwa 60 peresenti ya zopanga mu 2006.

Polyvinyl chloride, pvc, ndi imodzi mwa mapulasitiki otchuka omwe amagwiritsidwa ntchito pomanga ndi zomangamanga. Amagwiritsidwa ntchito pomwa madzi ndi mapazi amadzi, mafelemu a pawindo, pansi ndi zofunda za khoma, zingwe zina zambiri chifukwa cha mitengo yachikhalidwe monga nkhuni ndi galasi. Zogulitsazi nthawi zambiri zimakhala zopepuka, zochepa zotsika mtengo komanso zimapereka zabwino zambiri zamagalimoto.

Olimba ndi opepuka
Kukana kwa PVC's's's's's's's's's's's's's Kulemera, mphamvu zabwino, mphamvu zabwino ndi zabwino zaukadaulo kuti mugwiritse ntchito pomanga ndi ntchito zomanga.

Yosavuta kukhazikitsa
PVC ikhoza kudulidwa, yopangidwa, yokwezedwa komanso yolumikizidwa mosavuta mitundu yosiyanasiyana ya masitayilo osiyanasiyana. Kulemera kwake kumachepetsa zovuta zamavuto.

Cholimba
PVC imalimbana ndi nyengo, ma viod amasintha, kuwonongeka, kudabwitsidwa ndi kugwedezeka. Chifukwa chake ndi chisankho chomwe amakonda kwambiri kwa ambiri okhala ndi moyo wautali komanso zinthu zakunja. M'malo mwake, sing'anga kwakanthawi kochepa kwa 85 peresenti ya zopanga za PVC munyumbayi ndi zomanga.

Mwachitsanzo, akuti pali 75 peresenti ya mapaipi a PVC idzakhala ndi moyo pazaka 40 zotheka kukhala ndi moyo wazaka zana. Mwa ntchito zina monga masitepe a zenera ndi chingwe chotchinga, kafukufuku akuwonetsa kuti pafupifupi 20 peresenti ya iwo adzagwiranso ntchito zaka zoposa 40.

Mtengo wothandiza
PVC yakhala chinthu chodziwika bwino pazomanga zaka makumi angapo chifukwa cha zakuthupi zathupi komanso zaukadaulo zomwe zimapereka zabwino zabwino zothandizira. Monga momwe amapikisana kwambiri malinga ndi mtengo, mtengo uwu umalimbikitsidwanso ndi zinthu monga kulimba kwake, kukonzanso kwamoyo komanso kukonza kochepa.

Zinthu Zotetezeka
PVC siyopanda poizoni. Ndi zinthu zotetezeka komanso gwero lofunika kwambiri lomwe lakhala likugwiritsidwa ntchito kwa theka la zaka zana. Ndinso dziko lapansi

ofufuzidwa kwambiri komanso oyeserera bwino. Imakumana ndi miyezo yonse yamayiko a chitetezo ndi thanzi la zinthu ndi ntchito zomwe zimagwiritsidwa ntchito.

Phunziroli 'Kukambirana kwa ena mwazomwe zasayansi pankhani ya PVC' (1) ndi gulu la kafukufuku wa Interwealth Dissual ndi mafakitale (CSIRO) ku Australia ku Australia m'nyumba yake ndi zomangamanga sizikhudzanso malo ake.

Kulowetsa PVC ndi zinthu zina pazida zachilengedwe popanda kafukufuku wofufuza kapena maluso otsimikizika kumabweretsa ndalama zambiri. Mwachitsanzo, monga gawo la polojekiti yokonzanso nyumba ku Bermany, akuti zikuyembekezeredwa kuti m'malo mwa pvc mwa zida zina zimabweretsa mtengo pafupifupi 2,250 ma euro kwa nyumba yochepa.

Zoletsa kugwiritsa ntchito PVC pantchito zomanga sizimangokhala ndi zovuta zachuma komanso zimakhala ndi zoopsa, monga momwe zimakhalira ndi nyumba zotsika mtengo.

Moto wogwira moto
Monga zinthu zina zonse zolengedwa zomwe zimagwiritsidwa ntchito mu nyumba, kuphatikizapo pulasitiki zina, matabwa, zolemba zina zambiri. Zogulitsa za PVC komabe zimakhala zodzitchinjiriza, mwachitsanzo, ngati chizindikiritso chachotsedwa adzaleka kuyaka. Chifukwa cha zinthu zake zapamwamba za chlorine zimakhala ndi zinthu zachitetezo chamoto, zomwe zimakhala zabwino. Ndizovuta kuyika, kupanga kutentha ndikotsika kwenikweni ndipo amangokonda kwambiri madontho.

Koma ngati pali moto wokulirapo munyumba, zinthu za PVC zimawotcha ndipo zimatulutsa zinthu zoopsa ngati zinthu zina zonse zachilengedwe.
Chofunikira kwambiri choyambitsa moto ndi kaboni monoxide (CO), chomwe chimayambitsa 90 mpaka 95% yaimfa kuchokera kumoto. CO ndi wopha, popeza sitingathe kununkhiza ndipo anthu ambiri amafa mu moto ndikugona. Ndipo za Con Contited ndi zida zonse zolengedwa, zikhale zotanuka, kapangidwe kapena pulasitiki.

PVC komanso zida zina zimaperekanso acid. Izi zimatha kununkhira ndipo zimakwiyitsa, kupangitsa anthu kuyesera kuti athawe moto. Acid acid, hydrochloric acid (hcl), imalumikizidwa ndi PVC yoyaka. Mwa kudziwa kwathu, palibe womenyera moto yemwe adatsimikiziridwa kuti sanatsimikizedwe ndi HCL poizoni.

Zaka zingapo sizinafotokozedwe moto wopanda ma dioxins akuchita mbali yayikulu yolumikizirana komanso yoyezera mapulogalamu. Lero tikudziwa kuti Dioxins adatulutsa moto popanda zothandizira anthu omwe amatsatira maphunziro angapo pa moto. Chowonadi chofunikira ichi chadziwika ndi malipoti akuluakulu ndipo tikudziwa kuti ma carcinogens ena ambiri amatulutsidwa mu moto wonse wama hydrocarbons (pah) ndi zoopsa zambiri kuposa ma dioxin.

Chifukwa chake pali zifukwa zomveka zogwiritsira ntchito zinthu za PVC mu nyumba, popeza amachita bwino mwaluso, khalani ndi chuma chabwino komanso chachuma, ndikufanizira bwino ndi zinthu zina zotetezeka za moto.

Wabwino
PVC sikuti amayendetsa magetsi ndipo motero ndi chinthu chabwino kwambiri kugwiritsa ntchito magwiridwe amagetsi monga zotchingira mabaji.

Wotha ichi ndiichi
Katundu wa PVC amalola opanga ufulu wambiri posankha zatsopano ndikupanga mayankho omwe pvc amachita m'malo mwake kapena kukonza zinthu.

PVC yakhala zinthu zomwe amakonda polemba zikwangwani, zolemba zamkati, mafelemu a pawindo, makina amadzi atsopano, makina amadzi, malingaliro a chinsinsi komanso kugwiritsa ntchito ndalama zambiri.
