Iingenelo zemibhobho yePVC
1. Ukuthuthwa: Izinto ze-UPVC zinobunzima obuthile obuyi-1/10 kuphela kune-cast iron, nto leyo eyenza kube lula ukuzithumela nokuzifaka.
2. I-UPVC inokumelana okuphezulu kwe-asidi kunye ne-alkali, ngaphandle kwe-asidi ezinamandla kunye ne-alkalis ezikufutshane nendawo yokugcwala okanye ii-oxidizing agents ezinamandla kuxinzelelo oluphezulu.
3. Ayiqhubi: Ngenxa yokuba izinto ze-UPVC aziqhubi kwaye azidli xa zichatshazelwa yi-current okanye i-electrolysis, akukho mfuneko yokucubungula okongezelelweyo.
4. Akukho nkxalabo malunga nokukhuselwa komlilo kuba akunakutshisa okanye kukhuthaze ukutsha.
5. Ukufakela kulula kwaye akubizi kakhulu ngenxa yokusebenzisa i-PVC adhesive, eye yabonakala ithembekile kwaye ikhuselekile, kulula ukuyisebenzisa, kwaye ayibizi kakhulu. Ukusika nokudibanisa nako kulula kakhulu.
6. Ukumelana kakuhle kwemozulu kunye nokuchasana nokugqwala kweebhaktiriya kunye nefungus kwenza nantoni na ihlale ixesha elide.
7. Ukumelana okuncinci kunye nesantya esiphezulu sokuhamba kwamanzi: udonga olungaphakathi olugudileyo lunciphisa ukulahleka kolwelo, luthintela inkunkuma ukuba inamathele eludongeni lombhobho olugudileyo, kwaye lwenza ukugcinwa kube lula kwaye kungabizi kakhulu.

Iplastiki ayiyoPVC.
I-PVC yiplastiki esetyenziselwa izinto ezininzi enokusetyenziselwa izinto ezahlukeneyo, kuquka ifanitshala eqhelekileyo kunye neendawo zokwakha.
Ngaphambili, i-PVC yayiyeyona plastiki isetyenziswa kakhulu kwihlabathi kwaye yayineendlela ezahlukeneyo zokusetyenziswa. Isetyenziswa kakhulu kwizixhobo zokwakha, kwiimpahla zoshishino, kwizinto ezifunekayo zemihla ngemihla, kwisikhumba somgangatho, kwiithayile zomgangatho, kwisikhumba esenziwe ngokwenziwa, kwiipayipi, kwiintambo, nakwiintambo, kwiifilimu zokupakisha, kwiibhotile, kwiifayibha, kwizinto zokufaka amagwebu, nakwizinto zokuvala, phakathi kwezinye izinto.

I-Arhente yeHlabathi yoPhando ngoMhlaza ye-World Health Organisation yaqala yaqulunqa uluhlu lwezinto ezibangela umhlaza ngomhla wama-27 kweyeDwarha ngo-2017, kwaye i-polyvinyl chloride yayiyenye yeentlobo ezintathu zezinto ezibangela umhlaza kuloo luhlu.
I-polymer e-Amorphous eneempawu zesakhiwo sekristale, i-polyvinyl chloride yi-polymer ethatha indawo ye-atom enye ye-chlorine kwi-atom enye ye-hydrogen kwi-polyethylene. Olu xwebhu luhlelwe ngolu hlobo lulandelayo: n [-CH2-CHCl] Uninzi lwee-monomers ze-VCM zidibene ngendlela yentloko ukuya emsileni ukuze zenze i-polymer ethe tye eyaziwa ngokuba yi-PVC. Zonke ii-athomu zekhabhoni zidityaniswe ngamabhondi kwaye zihlelwe ngendlela ye-zigzag. Yonke i-atom yekhabhoni ine-sp3 hybrid.

Itsheyini ye-PVC molecular inesakhiwo esiqhelekileyo se-syndiotactic esifutshane. I-syndiotacticity iyanda njengoko ubushushu be-polymerization busehla. Kukho izakhiwo ezingazinzanga eziquka isakhiwo sentloko ukuya entloko, i-branched chain, i-double bond, i-allyl chloride, kunye ne-tertiary chlorine kwisakhiwo se-polyvinyl chloride macromolecular, nto leyo ebangela iingxaki ezifana nokumelana nokuguquguquka kobushushu obuphantsi kunye nokumelana nokwaluphala. Ezi ziphene zinokulungiswa emva kokuba zibonakala zidibene.

Indlela yoqhagamshelo lwePVC:
1. Kusetyenziswa iglu ethile ukudibanisa izixhobo zepayipi zePVC; iglu kufuneka ishukunyiswe phambi kokuba isetyenziswe.
2. Icandelo lesokhethi kunye nombhobho wePVC kufuneka zicocwe. Okukhona kungekho sithuba sininzi phakathi kwezisokhethi, kokukhona umphezulu wamalungu ufanele ube bushelelezi. Emva koko, xubha iglu ngokulinganayo kwisokhethi nganye uze uxube iglu kabini ngaphandle kwesokhethi nganye. Emva kwemizuzwana engama-40 yomile, beka. Beka iglu kude kwaye uqaphele ukuba ixesha lokomisa kufuneka lonyuswe okanye lincitshiswe ngokuhambelana nemozulu.
3. Umbhobho kufuneka uzaliswe kwakhona emva kweeyure ezingama-24 emva koqhagamshelo olomileyo, umbhobho kufuneka ufakwe emseleni, kwaye ukumanzisa akuvumelekanga ngokungqongqo. Xa ugcwalisa kwakhona, gcina iindawo ezidibeneyo, gcwalisa indawo ejikeleze umbhobho ngesanti, kwaye uzalise kwakhona kakhulu.
4. Ukuze udibanise umbhobho wePVC nombhobho wentsimbi, coca indawo edibana kuyo umbhobho wentsimbi odibeneyo, uwufudumeze ukuze uthambise umbhobho wePVC (ngaphandle kokuwutshisa), uze ufake umbhobho wePVC kumbhobho wentsimbi ukuze uphole. Isiphumo siya kuba ngcono ukuba kufakwe iihupu ezenziwe ngombhobho wentsimbi.
Imibhobho yePVCingaqhagamshelwa ngenye yeendlela ezine:
1. Ukuba umbhobho wonakaliswe kakhulu, yonkeumbhobhokufuneka itshintshwe. Isixhumi esineeport ezimbini singasetyenziswa ukwenza oku.
2. Indlela yokunyibilikisa ingasetyenziswa ukunqanda ukuvuza kweglue yesinyibilikisi. Kule ndawo, amanzi ombhobho oyintloko ayakhutshwa, nto leyo edala uxinzelelo olubi lombhobho ngaphambi kokuba iglue ifakwe emngxunyeni kwindawo evuzayo. Iglue iya kutsalwa kwiimbobo ngenxa yoxinzelelo olubi lombhobho, nto leyo ethintela ukuvuza.
3. Eyona nto iphambili ekujoliswe kuyo kwinkqubo yokulungisa i-sleeve bonding kukuvuza kwe-casing ngokusebenzisa imingxunya emincinci. Lo mbhobho we-caliber ofanayo ngoku ukhethwa ukusika ixesha elide kwaye ubude bawo buqala kwi-15 ukuya kwi-500 px. Umphezulu wangaphakathi we-casing kunye nomphezulu wangaphandle we-casing olungisiweyo uqhagamshelwe kwiindawo ezidibeneyo ngokwenkqubo esetyenzisiweyo. Emva kokufaka iglu, umphezulu uyarhabaxa, uze emva koko ubotshelelwe ngokuqinileyo kumthombo wokuvuza.
4. Ukwenza isisombululo se-resin usebenzisa i-epoxy resin curing agent, sebenzisa indlela ye-glass fiber. Ilukwa ngokulinganayo kumphezulu wombhobho okanye kwindawo evuzayo emva kokuba ifakwe kwisisombululo se-resin ngelaphu le-glass fiber, kwaye emva kokuba icoliwe, iba yi-FRP.
