PVC kupisa stabilizerskuita basa rakakosha mukuona kushanda uye kusimba kwepombi dzePVC. Aya ma stabilizers anowedzera anoshandiswa kuchengetedza PVC zvinhu kubva mukuora kunokonzerwa nekuratidzwa nekupisa, chiedza uye oksijeni. Muchikamu chino, tichaongorora mashandisirwo ePVC heat stabilizers mumapombi ePVC uye kukosha kwawo pakuchengetedza mhando yepombi.
PVC, kana polyvinyl chloride, chinhu chinogoneka chinowanzoshandiswa muindasitiri yekuvaka kune akasiyana maapplication, anosanganisira mapaipi, mafittings uye conduits. Mapombi ePVC anoshandiswa zvakanyanya mukupa mvura, kudhiraivha, kudiridza uye masisitimu ekuchenesa tsvina nekuda kwekugara kwawo, kusagadzikana kwekuora, uye nyore kuisa. Nekudaro, zvinhu zvePVC zvinowanzodzikira kana zvakafumurwa nekupisa uye chiedza, zvichikonzera kurasikirwa kwesimba remagetsi uye kushanduka.
Kukunda dambudziko iri, PVC heat stabilizers anoshandiswa kuchengetedza iyo PVC zvinhu kubva mukupisa kwekupisa panguva yekugadzirisa uye sevhisi hupenyu hwePVC pombi. Chinangwa chezvigadziriso izvi ndechekudzivisa maitiro ekuora mwoyo anoitika apo PVC inoratidzirwa nekupisa uye chiedza, nokudaro kuwedzera hupenyu hwebasa hwepombi uye kuchengetedza maitiro ayo emagetsi.
Kune marudzi akawanda ePVC heat stabilizers anoshandiswa pamapaipi ePVC, anosanganisira lead-based stabilizers, tin-based stabilizers, calcium-based stabilizers uye organic-based stabilizers. Imwe neimwe mhando ye stabilizer ine yayo yakasarudzika zvivakwa uye mabhenefiti, uye kusarudza iyo yakanyanya kugadzikana zvinoenderana nezvinodiwa chaizvo zvePVC pombi application yako.
Lead-based stabilizers, senge lead stearate uye lead trivalent sulfate, yakashandiswa zvakanyanya munguva yakapfuura nekuda kwekudzikama kwemafuta uye kudhura-kushanda. Zvisinei, nemhaka yezvinetso zvemhoteredzo noutano, nyika dzakawanda dzakarega kushandiswa kwemichina inodzikamisa mutobvu ndokuitsiva neinodzikamisa.
Tin-based stabilizers, senge dibutyltin dilaurate uye tributyltin oxide, inozivikanwa nekudzika kwayo kwepamusoro kwekushisa uye kujeka, zvichiita kuti ive yakakodzera kune zvikumbiro uko kuchengetwa kwemavara kwakakosha. Aya ma stabilizer zvakare anodzivirira zvinobudirira PVC pombi kubva mukuora panguva yekugadziriswa uye kubuda kunze.
Calcium-based stabilizers, yakadai secalcium stearate uye calcium zinc stabilizers, isiri-chepfu dzimwe nzira kune lead-based stabilizers uye inowanzoshandiswa mukugadzira mapaipi ePVC emvura yekunwa uye kurongedza chikafu. Aya ma stabilizer ane kugadzikana kwakanaka kwekupisa uye kuramba kwemamiriro ekunze, zvichiita kuti ive yakakodzera kushandiswa kwekunze.
Organic stabilizers, senge epoxidized soybean oiri uye methyltin mercaptide, inotorwa kubva kune yakasarudzika masosi uye inofarirwa nekuda kwehushamwari hwadzo uye husina chepfu. Aya ma stabilizer anonyatso chengetedza mapaipi ePVC kubva mukupisa kwekupisa uye anokodzera maapplication ane yakasimba mitemo yezvakatipoteredza.
Munguva yekugadzira mapombi ePVC, PVC heat stabilizers inowedzerwa kuPVC resin panguva yekusanganiswa kuita musanganiswa wakafanana. Mastabilizers anonyatso kuvharisa maitiro ekudzikisira anokonzerwa nekupisa uye chiedza nekugadzira macomplexes ane PVC polymer cheni. Izvi zvinovimbisa kuti PVC pombi inochengetedza simba rayo remuchina, kugadzikana kwemavara uye kutendeseka kwehupenyu hwese hwesevhisi.
Munguva yehupenyu hwesevhisi yePVC mapaipi, kuratidzwa kune zvekunze zvinhu zvakaita sechiedza chezuva, kushanduka kwetembiricha, makemikari, nezvimwe zvinomhanyisa kuparara kwezvinhu zvePVC. PVC heat stabilizers inoita basa rakakosha mukuchengetedza mapaipi kubva kune izvi zvinosvibisa zvinhu, kuve nechokwadi chekuita kwavo kwenguva refu uye kuvimbika.
Iko kushandiswa kwePVC heat stabilizers kwakakosha kuchengetedza kunaka uye kuita kwePVC pombi. Aya ma stabilizer anochengetedza iyo PVC zvinhu kubva mukupisa kwekupisa uye inova nechokwadi chekuti pombi inochengetedza michina yayo, kugadzikana kwemavara uye kuperera. Sezvo stabilizer tekinoroji ichifambira mberi, ikozvino pane akasiyana sarudzo yekusangana nezvinodiwa zvakasiyana zvePVC pombi maapplication. Sezvo kudiwa kwepombi dzePVC dzemhando yepamusoro uye dzakasimba dzichiramba dzichikura, kukosha kwePVC heat stabilizers muindasitiri yepombi yePVC hakugone kuwedzeredzwa.
