Vavu ya mpira wa pulasitiki imagwiritsidwa ntchito makamaka kudula kapena kulumikiza sing'anga mu payipi, komanso imagwiritsidwa ntchito pakuwongolera ndi kuwongolera madzi.Valve ya mpira ili ndi zabwino zambiri, monga kukana kwamadzimadzi otsika, kulemera kopepuka, mawonekedwe owoneka bwino komanso owoneka bwino, kukana kwa dzimbiri, ntchito zosiyanasiyana, zida zaukhondo komanso zopanda poizoni, kukana kuvala, kusokoneza kosavuta, kukonza kosavuta.N’chifukwa chiyani lili ndi ubwino wambiri chonchi?Iyi ndiye mfundo yomwe tikufufuza lero - zakuthupi.
Zida zosiyanasiyana zimakhala ndi makhalidwe osiyanasiyana, ndipo zikapangidwa kukhala valavu ya mpira wa pulasitiki, valavu ya mpira wa pulasitiki idzapatsidwa makhalidwe a zinthuzo.Masiku ano, pali zinthu zambiri zomwe zimagwiritsidwa ntchito popanga mavavu a pulasitiki, monga UPVC, RPP, PVDF, PPH, CPVC, etc.
UPVC nthawi zambiri imatchedwa kuti PVC yolimba, yomwe ndi utomoni wa amorphous thermoplastic wopangidwa ndi vinyl chloride monomer ndi polymerization reaction kuphatikiza zowonjezera zina (monga stabilizers, lubricant, fillers, etc.) UPVC mavavu ampira si acid-, alkali- ndi dzimbiri- kugonjetsedwa, komanso kukhala mkulu mawotchi mphamvu ndi kukwaniritsa mfundo dziko ukhondo madzi akumwa.Product kusindikiza ntchito ndi zabwino kwambiri, chimagwiritsidwa ntchito zomangamanga, mankhwala, mankhwala, petrochemical, zitsulo, ulimi, ulimi wothirira, aquaculture ndi madzi ena boma dongosolo msewu.-10 ℃ mpaka 70 ℃ kutentha osiyanasiyana.
RPP ndi zida zowonjezeredwa za polypropylene.Ma valve a mpira ophatikizidwa ndikuwumbidwa ndi ma jakisoni a RPP ali ndi kukana kwa dzimbiri, moyo wautali wautumiki, kusinthasintha kosinthika komanso kugwiritsa ntchito kosavuta.-20 ℃ mpaka 90 ℃ kutentha osiyanasiyana.
Polyvinylidene fluoride, PVDF mwachidule, ndi fluoropolymer yosagwira ntchito kwambiri ya thermoplastic.Ndiwotchingira moto, osatopa komanso osavuta kuthyoka, odana ndi kuvala, zinthu zabwino zodzipaka mafuta okha, zida zabwino zotchinjiriza.Valavu ya mpira ya PVDF ili ndi kukhazikika kwamankhwala, kukana kwamankhwala komanso kukhazikika kwa kutentha.Itha kugwiritsidwa ntchito kwa nthawi yayitali pakutentha kwa -40 ℃ mpaka 140 ℃, ndipo imatha kukana mchere, asidi, alkali, zonunkhira za hydrocarbon, halogen ndi media zina kupatula zosungunulira zamphamvu.
CPVC ndi mtundu watsopano wa pulasitiki waukadaulo wokhala ndi ntchito yabwino.Chogulitsacho ndi choyera kapena chopepuka chachikasu chosakoma, chosanunkha, chopanda poizoni, ma granules kapena ufa.cpvc mpira valavu kaya asidi, alkali, mchere, klorini, makutidwe ndi okosijeni chilengedwe, poyera mlengalenga, kukwiriridwa mu nthaka zikuwononga, ngakhale pa 95 ℃ kutentha kwambiri, mkati ndi kunja si dzimbiri, akadali amphamvu ndi odalirika monga poyamba. kukhazikitsa.
