Mabhenefiti emapaipi ePVC
1. Kutakurwa: Zvinhu zveUPVC zvine simba guru rekukura rinosvika chikamu chimwe mugumi chesimbi yakakandwa, zvichiita kuti zvisadhure kutumira nekuisa.
2. UPVC ine simba guru rekudzivirira acid nealkali, kunze kweacids dzakasimba nealkali dziri pedyo nenzvimbo yekuzara kana kuti makemikari ane simba re oxidizing ari pahuwandu hwakanyanya.
3. Hazvifambise: Nekuti zvinhu zveUPVC hazvifambise uye hazvikanganisi kana zvasangana nemagetsi kana electrolysis, hapana imwe nzira yekugadzirisa inodiwa.
4. Hapana kunetseka nezvekudzivirira moto nekuti hazvigone kupisa kana kukurudzira kutsva.
5. Kuisa kwacho kuri nyore uye hakudhuri nekuda kwekushandisa PVC glue, iyo yaratidza kuti yakavimbika uye yakachengeteka, iri nyore kushandisa, uye isingadhuri. Kucheka nekubatanidza zvakare zviri nyore.
6. Kusashanda zvakanaka mumamiriro ekunze uye kusashanda zvakanaka kubva mukuora kwemabhakitiriya nefungus kunoita kuti chero chinhu chigare kwenguva refu.
7. Kusasimba kudiki uye kuyerera kwakanyanya: madziro emukati akatsetseka anoderedza kurasikirwa kwemvura inoyerera, anodzivirira marara kuti asanamatira pamadziro epombi akatsetseka, uye anoita kuti kugadzirisa kuve nyore uye kusadhure.

Plastiki haisi PVC.
PVC ipurasitiki inoshandiswa pamabasa akasiyana-siyana inogona kushandiswa pazvinhu zvakasiyana-siyana, kusanganisira fenicha yakajairika nenzvimbo dzekuvaka.
Kare, PVC ndiyo yainyanya kushandiswa pasi rose uye yaishandiswa zvakasiyana-siyana. Inoshandiswa zvakanyanya muzvinhu zvekuvaka, zvinhu zvemaindasitiri, zvinhu zvinodiwa zuva nezuva, dehwe repasi, mataira epasi, dehwe rekugadzira, mapaipi, waya, netambo, mafirimu ekurongedza, mabhodhoro, fibers, zvinhu zvinofuridzira furo, uye zvinhu zvekuvhara, pakati pezvimwe zvinhu.

Sangano reWorld Health Organisation's International Agency for Research on Cancer rakatanga kunyora runyorwa rwezvinhu zvinokonzera kenza musi wa27 Gumiguru 2017, uye polyvinyl chloride yaive imwe yemhando nhatu dzezvinhu zvinokonzera kenza dziri pane runyorwa irworwo.
Polymer isina chimiro ine zvisaririra zvemagadzirirwo ekristalline, polyvinyl chloride ipolymer inotsiva atomu imwe yechlorine neatomu imwe yehydrogen mu polyethylene. Gwaro iri rakarongwa seizvi: n [-CH2-CHCl] Ruzhinji rwemamonomer eVCM rwakabatanidzwa muchimiro chemusoro-ku-muswe kuti rugadzire polymer yakatsetseka inozivikanwa sePVC. Maatomu ese ecarbon anobatanidzwa pamwe chete nezvisungo uye akarongwa muchimiro che zigzag. Atomu yega yega yecarbon ine sp3 hybrid.

Cheni yePVC molecular ine chimiro chenguva pfupi che syndiotactic. Syndiotacticity inokwira kana tembiricha yepolymerization ichidzikira. Kune zvivakwa zvisina kugadzikana zvinosanganisira chimiro chemusoro-ku-musoro, cheni ine branched, double bond, allyl chloride, uye tertiary chlorine muchimiro che polyvinyl chloride macromolecular, izvo zvinoguma nematambudziko akadai sekusagadzikana kwekushisa uye kuramba kukwegura. Zvikanganiso zvakadaro zvinogona kugadziriswa mushure mekunge zvaita sezvine cross-linked.

Nzira yekubatanidza PVC:
1. Guruu rakati rinoshandiswa kubatanidza zvinhu zvepaipi zvePVC; guruu rinofanira kuzununguswa risati rashandiswa.
2. Chikamu chesoketi nepaipi yePVC zvinoda kucheneswa. Kana nzvimbo iri shoma pakati pemasoketi, pamusoro pemajoini panofanira kunge pakapfava. Wobva wakwesha guruu zvakaenzana musoketi yega yega wokwesha guruu kaviri kunze kwesoketi yega yega. Masekonzi makumi mana mushure mekuoma, isa guruu. Isa guruu kure wocherechedza kana nguva yekuomesa ichifanira kuwedzerwa kana kuderedzwa zvichienderana nemamiriro ekunze.
3. Pombi inofanira kuzadzwa zvakare maawa makumi maviri nemana mushure mekubatana kwakaoma, pombi inofanira kuiswa mugomba, uye kunyorova hakubvumirwi zvachose. Pakuzadza zvakare, chengetedza majoini, zadza nzvimbo yakakomberedza pombi nejecha, uye vhara zvakare zvakanyanya.
4. Kuti ubatanidze pombi yePVC nepombi yesimbi, chenesa nzvimbo inoungana pombi yesimbi yakasungirirwa, ipise kuti ipfavedze pombi yePVC (isina kuipisa), wobva waisa pombi yePVC mupombi yesimbi kuti itonhore. Mugumisiro wacho uchava nani kana hoops dzakagadzirwa nepombi yesimbi dzikaiswa.
Mapaipi ePVCinogona kubatanidzwa neimwe yenzira ina:
1. Kana pombi yacho yakakuvara zvakanyanya, zvesepombiinofanira kutsiviwa. Chinongedzo chine mapombi maviri chinogona kushandiswa kuita izvi.
2. Nzira yekunyungudutsa mvura inogona kushandiswa kumisa kubuda kweglue re solvent. Panguva iyi, mvura yepombi huru inodonhedzwa, zvichiita kuti pave nekumanikidzwa kweglue risati rapinzwa mugomba riri panzvimbo inobuda mvura. Gurue rinodhonzwa mumaburi nekuda kwekumanikidzwa kweglue repombi, zvichimisa kubuda kwemvura.
3. Chinangwa chikuru chekugadzirisa chisungo chemaoko ndechekubuda kwekasi kuburikidza nepakati pemaburi madiki nemaburi. Pombi imwecheteyo inosarudzwa kuti ichekwe kwenguva refu uye ine hurefu hwe15 kusvika 500 px. Pamusoro pekasi nepamusoro pepombi yakagadziriswa zvakabatana pamajoini zvichienderana nemaitiro anoshandiswa. Mushure mekushandisa guruu, pamusoro payo panobva paoma, uye inobva yasungirirwa zvakasimba panobva pabuda mvura.
4. Kuti ugadzire resin solution uchishandisa epoxy resin curing agent, shandisa nzira yegirazi fiber. Inorukwa zvakaenzana pamusoro pepombi kana panobuda mvura mushure mekunyikwa mu resin solution nejira regirazi fiber, uye mushure mekuoma, inova FRP.
