Iinzuzo zemibhobho yePVC
1. Ukuthuthwa: Izinto ze-UPVC zinobunzima obuthile obunye kuphela kwishumi lentsimbi yentsimbi, okwenza ukuba kungabizi kakhulu ukuhambisa nokufaka.
2. I-UPVC ine-asidi ephezulu kunye nokuchasana kwe-alkali, ngaphandle kwe-acids eqinile kunye ne-alkali kufuphi ne-saturation point okanye i-agent e-oxidizing enamandla ekugxininiseni okuphezulu.
3. I-non-conductive: Ngenxa yokuba izinto ze-UPVC aziyi-conductive kwaye ayidli xa ibonakaliswe ngoku okanye i-electrolysis, akukho mfuneko yokongeziweyo.
4. Akukho nkxalabo malunga nokukhuselwa komlilo kuba awukwazi ukutshisa okanye ukukhuthaza ukutsha.
5. Ufakelo lulula kwaye lungabizi kakhulu ngenxa yokusetyenziswa kwe-PVC yokunamathela, ebonakalise ukuba inokwethenjelwa kwaye ikhuselekile, kulula ukuyisebenzisa, kwaye ayibizi.Ukusika kunye nokudibanisa nazo zithe ngqo.
6. Ukuchasana kwemozulu okugqwesileyo kunye nokuchasana ne-bacterial and fungal corrosion kwenza nantoni na ehlala ixesha elide.
7. Ukuchasana okuncinci kunye nesantya esiphezulu sokuhamba: udonga lwangaphakathi olugudileyo lunciphisa ukulahleka kwe-fluidity, luthintela i-debris ukuba ibambelele eludongeni lombhobho ogudileyo, kwaye yenza ukugcinwa kube lula kwaye kungabizi.

Iplastiki ayikho iPVC.
I-PVC yiplastiki yemisebenzi emininzi enokuthi isetyenziswe kwizinto ezahlukeneyo, kubandakanywa nempahla eqhelekileyo kunye neziza zokwakha.
Ngaphambili, iPVC yayiyeyona isetyenziswa kakhulu emhlabeni kwaye yayisetyenziswa ngeendlela ezahlukeneyo.Isetyenziswa kakhulu kwizinto zokwakha, iimpahla zamashishini, iimfuno zemihla ngemihla, isikhumba somgangatho, iithayile zomgangatho, isikhumba sokwenziwa, imibhobho, iingcingo, kunye neentambo, iifilimu zokupakisha, iibhotile, iifayibha, izinto ezinogwebu, kunye nezinto zokutywina, phakathi kwezinye izinto.

I-Arhente yeHlabathi yezeMpilo yeHlabathi yoPhando lweCancer yaqala yaqulunqa uluhlu lwee-carcinogens ngo-Oktobha 27, 2017, kunye ne-polyvinyl chloride yenye yeentlobo ezintathu ze-carcinogens kuloluhlu.
Ipolymer eAmorphous enemigca yesakhiwo sekristale, i-polyvinyl chloride yipolymer ethatha indawo yeathom yeklorin enye kwi-athomu ye-hydrogen kwi-polyethylene.Olu xwebhu luhlelwe ngolu hlobo lulandelayo: n [-CH2-CHCl] Uninzi lwee-monomers ze-VCM zihlangene kwi-head-to-tail configuration ukuze zenze i-polymer yomgca eyaziwa ngokuba yi-PVC.Zonke iiathomu zekhabhoni zidityaniswe kunye ngamabhondi kwaye zicwangciswe ngendlela ye-zigzag.Yonke iathom yekhabhoni ine-sp3 hybrid.

Itsheyini ye-PVC yeemolekyuli inesakhiwo esifutshane se-sydiotactic rhoqo.I-sydiotacticity iyenyuka njengoko ubushushu be-polymerization buhla.Kukho izakhiwo ezingazinzanga ezibandakanya i-head-to-head structure, i-branched chain, i-double bond, i-allyl chloride, kunye ne-tertiary chlorine kwi-polyvinyl chloride isakhiwo se-macromolecular, esibangela ukungahambi kakuhle njengokuchasana kwe-thermal deformation kunye nokumelana nokuguga.Iziphene ezinjalo zinokulungiswa emva kokubonakala zidibene.

Indlela yokudibanisa yePVC:
1. Iglue ethile isetyenziselwa ukujoyina i-PVC fittings pipe;i-adhesive kufuneka ishukunyiswe ngaphambi kokusetyenziswa.
2. Icandelo le-socket kunye nombhobho wePVC kufuneka zicocwe.Indawo encinci ekhoyo phakathi kweziseko, i-smooth surface of joints kufuneka ibe.Emva koko, xuba ngokulinganayo iglu kwisokethi nganye kwaye kabini ukuxubha iglu kumphandle wesokethi nganye.Imizuzwana engama-40 emva kokumisa, beka Beka iglue kude kwaye ubeke ingqalelo ukuba ixesha lokumisa kufuneka linyuswe okanye linciphe ngokuhambelana nemozulu.
3. Umbhobho kufuneka ugcwaliswe ngasemva kwiiyure ezingama-24 emva koqhagamshelo olomileyo, umbhobho kufuneka ufakwe emhadini, kwaye ukumanzi akuvumelekanga ngokungqongqo.Xa ubuyisela umva, gcina amalunga, gcwalisa indawo ejikeleze umbhobho ngesanti, kwaye ubuyisele ngokubanzi.
4. Ukudibanisa umbhobho wePVC kumbhobho wensimbi, hlambulula umdibaniso wombhobho wensimbi odibeneyo, ushushu ukuthambisa umbhobho wePVC (ngaphandle kokuwutshisa), uze ufake umbhobho wePVC kumbhobho wensimbi ukuze upholile.Isiphumo siya kuba ngcono ukuba i-hoops eyenziwe ngombhobho wensimbi ifakwe.
Imibhobho yePVCinokudityaniswa ngenye yeendlela ezine:
1. Ukuba umbhobho ugcine umonakalo omkhulu, ugqityiweumbhobhokufuneka kutshintshwe.Isidibanisi sezibuko ezimbini singasetyenziswa ukwenza oku.
2. Indlela ye-solvent ingasetyenziselwa ukumisa ukuvuza kweglue ye-solvent.Ngeli xesha, amanzi ombhobho oyintloko akhutshwe, okwenza uxinzelelo olubi lombhobho ngaphambi kokuba iglue ifakwe emngxunyeni kwindawo yokuvuza.Iglu iya kutsalwa kwiipores ngenxa yoxinzelelo olubi lombhobho, ukumisa ukuvuza.
3. Eyona njongo iphambili yenkqubo yokubopha imikhono kukuvuza kwecasing ngokusebenzisa iintanda ezincinci kunye nemingxuma.Umbhobho we-caliber ofanayo ngoku ukhethwa ukusika i-longitudinal kunye nobude obude ukusuka kwi-15 ukuya kwi-500 px.Umphezulu wangaphakathi we-casing kunye nomphandle wangaphandle wombhobho olungisiweyo udibaniswa kumalungu ngokuhambelana nenkqubo esetyenzisiweyo.Emva kokufaka iglue, umphezulu urhabaxa, kwaye emva koko uqiniswe ngokuqinileyo kwindawo yokuvuza.
4. Ukwenza isisombululo se-resin usebenzisa i-epoxy resin yokunyanga i-agent, sebenzisa i-glass fiber method.Ilukwe ngokulinganayo kumphezulu wombhobho okanye isiphambuka esivuzayo emva kokuba ifakwe kwisisombululo sentlaka ngelaphu leglasi losinga, kwaye emva kokunyanga, iba yiFRP.
