Xabagta laalista PVC ee soo saarista tuubooyinka PVC iyo qalabyada
Xabagta laalista PVC ee soo saarista tuubooyinka PVC iyo qalabyada,
Xabagta laalista PVC si loo soo saaro tuubooyinka PVC iyo qalabyada,
Tuubbada PVC (oo loo qaybiyo tuubooyinka PVC-U, tuubbada PVC-M iyo tuubada PVC-O) tuubbada polyvinyl chloride adag, oo laga sameeyay xabagta PVC oo leh stabilizer, saliidayn iyo qaabaynta kale ee cadaadinta kulul, waa kan ugu horreeya ee la sameeyo oo lagu dabaqo caag tuubo.
Tuubbada PVC-U waxay leedahay iska caabin adag oo daxalka ah, isku xirnaanta fudud, qiimo jaban iyo texture adag, laakiin sababta oo ah dillaaca PVC-U monomer iyo waxyaabaha lagu daro, waxay ku habboon tahay oo keliya nidaamka sahayda biyaha halkaasoo heerkulka gaadiidku uusan ka badnayn 45 ° C. Tuubooyinka caaga ah waxaa loo isticmaalaa codsiyada dareeraha, biyaha wasakhda ah, kiimikooyinka, dareerayaasha kululaynta iyo qaboojiyaha, cuntada, dareeraha saafiga ah, dhoobada, gaaska, hawo cadaadis leh iyo nidaamka faakuumka.
Tuubbada Pvc-o, magaca Shiinaha ee biaxial oriented polyvinyl chloride, waa qaabkii ugu dambeeyay ee horumarinta tuubada PVC, iyada oo loo marayo habka habaynta hanuuninta gaarka ah si loo soo saaro tuubada, tuubada PVC-U oo ay soo saartay habka extrusion ee fidinta axial iyo fidinta radial, sidaas darteed in molecules silsiladda dheer ee PVC ee tuubada ee habka biaxial, Tuubo cusub oo PVC ah oo leh xoog sare, adag oo sarreeya, iska caabin saameyn sare leh iyo iska caabin daal ah ayaa la helay.
Faahfaahinta alaabta
PVC waxay ku timaadaa laba nooc oo aasaasi ah: adag iyo dabacsanaan.Noocyada adag ee PVC waxaa loo isticmaali karaa tuubooyinka, albaabada iyo daaqadaha.Waxa kale oo loo isticmaali karaa dhalooyinka, baakadaha kale ee aan cuntada ahayn, iyo bangiyada ama kaararka xubinnimada.Waxa kale oo laga samayn karaa alaab la dhammeeyey oo jilicsan, taas oo ka dhigaysa mid aad u dabacsan marka lagu daro balaastikada, inta badan phthalates.Foomkan, waxaa loo isticmaali karaa tuubooyinka jilicsan, fiilooyinka fiilooyinka, maqaar ku dayasho, calaamad jilicsan, alaab la buufiyo, iyo codsiyo badan oo aan ahayn caag.
Polyvinyl chloride waxaa laga samayn karaa ethylene, koloriin iyo kicinta falcelinta beddelka.Sababtoo ah iska caabbinta dabka iyo caabbinta kulaylka, PVC waxaa si ballaaran loo isticmaalaa dhammaan qaybaha nolosha iyo noocyada kala duwan ee alaabta: maqaarka fiilada, maqaarka fiber indhaha, kabaha, shandadadaha, bacaha, qurxinta, calaamadaha iyo boodhadhka, qalabka qurxinta dhismaha, alaabta guriga, laalaadinta qurxinta, rollers, tubooyinka, alaabta lagu ciyaaro (sida talyaaniga caanka ah "Rody" faraska boodboodka), sawiro animation, daahyada albaabka, albaabada duuban, sahayda caawimada ah, galoofyada, waraaqaha cuntada, qaar moodada ah, iwm.
Xirmooyinka PVC SG5 ee lagu soo saaro habka joojinta ayaa ku habboon soo saarista tuubooyinka PVC ee adag iyo profiles
