Ukusetshenziswa kwePVC Heat Stabilizer yamapayipi e-PVC

Abaqinisi bokushisa kwe-PVCdlala indima ebalulekile ekuqinisekiseni ukusebenza nokuqina kwamapayipi e-PVC. Abakhuthazeli bangezengezo ezisetshenziselwa ukuvikela izinto ze-PVC ekuwohlokeni okubangelwa ukuvezwa kokushisa, ukukhanya nomoya-mpilo. Kulesi sihloko, sizohlola ukusetshenziswa kwe-PVC Heat Stalilizers kumapayipi e-PVC nokubaluleka kwawo ngokugcina ikhwalithi yamapayipi.

I-PVC, noma i-polyvinyl chloride, ingabe impahla eguquguqukayo esetshenziswa kakhulu embonini yezokwakha izinhlobonhlobo zezicelo, kufaka phakathi amapayipi, ukufakwa kanye nemikhuba. Amapayipi e-PVC asetshenziswa kabanzi ekuhlinzekeni kwamanzi, ukudonsa, ukunisela kanye nezinhlelo zokwehla kwendle zendle ngenxa yokuqina kwawo, ukumelana nokugqwala, nokufakwa kalula. Kodwa-ke, izinto ze-PVC zivame ukwehla lapho zivezwa ukushisa nokukhanya, okuholela ekulahlekelweni amandla okusebenza kanye nokuzikhulula.

Ukunqoba le nselelo, abaqinisi bokushisa kwe-PVC basetshenziselwa ukuvikela impahla ye-PVC ekuwohlokeni okushisayo ngesikhathi sokucubungula kanye nempilo yenkonzo yamapayipi e-PVC. Inhloso yalaba bakhuthazeli ukuvimba ukusabela kokonakaliswa okwenzeka lapho i-PVC ivezwa ukushisa nokukhanya, ngaleyo ndlela yandisa impilo yenkonzo yepayipi futhi ilondoloze izakhiwo zayo zemishini.

Kunezinhlobo eziningi ze-PVC Heat Stuvilizers ezisetshenziselwa amapayipi e-PVC, kufaka phakathi ukuqina okusekelwe ekuholeni, abaqiniswa abasuselwa ku-Tin-based, abaqinisi abasuselwa ku-calcium kanye nabaqinisi be-organic. Uhlobo ngalunye lwe-Stabilizer lunezakhiwo zalo ezihlukile nezinzuzo, futhi ukhetha i-Stabilizer efanele kakhulu kuncike kwizidingo ezithile zohlelo lwakho lokusebenza lwePVC Pubane.

Abaqiniswa abasezingeni eliphakeme, abanjengomhogela ukuhogela nokuhola i-trivatent sulfate, basetshenziswe kabanzi esikhathini esedlule ngenxa yokuqina kwabo okuhle kakhulu kanye nokusebenza kwezindleko. Kodwa-ke, ngenxa yezinkinga zemvelo nezempilo, amazwe amaningi afake ukusetshenziswa kwezikhuthazi ezisuselwa ekuholeni futhi wazithathela abanye abaqiniswayo.

Abaqiniswa abasuselwa ku-Tin-based, njenge-DIBUTYLLTIN BILUNTATE NE-TRIBUTYLTIN KIDE, bayaziwa ngokuqina kwabo okuphezulu nokucaca, okwenza balungele izinhlelo zokusebenza lapho ukugcinwa kombala kubalulekile. Abakhuthazeleli baphinde bavikele ngempumelelo ipayipi le-PVC ekuwohlokeni ngesikhathi sokucubungula nokuvezwa kwangaphandle.

Abaqiniswa abasuselwa kwi-calcium, njenge-calcium stearate kanye ne-calcium zinc Stungotives, ezinye izindlela ezingezona ezinobuthi kubagcini bokugcina abasebenza ngokuhola futhi bavame ukusetshenziswa ekukhiqizweni kwamapayipi e-PVC okuphuza amanzi nokudla. Lezi zibalo zinokuqina okuhle okushisayo kanye nokumelana nesimo sezulu, okwenza balungele izinhlelo zokusebenza zangaphandle.

Abaqiniswa be-organic, njengamafutha e-soybean e-soya kanye ne-methyltin merbeetateride, athathwe emithonjeni yemvelo futhi athandwa ngenxa yezakhiwo zawo ezinobungane nezemvelo. Abakhuthazeleli bavikele ngempumelelo amapayipi e-PVC ekuwohlokeni okushisayo futhi alungele izinhlelo zokusebenza ezinemithethonqubo eqinile yemvelo.

Ngesikhathi senqubo yokukhiqiza yamapayipi e-PVC, abaqinisi bokushisa kwe-PVC bangezwa ku-PVC Resin ngesikhathi senqubo ehlanganisiwe ukwakha ingxubevange ye-homogeneous. Abaqinisi bevimbela ngempumelelo ukusabela kokulimazeka okubangelwa ukushisa nokukhanya ngokwakha izakhiwo nge-PVC polymer chains. Lokhu kuqinisekisa ukuthi ipayipi le-PVC ligcina amandla alo emishini, ukuqina kombala kanye nobuqotho obukhulu kuyo yonke impilo yayo yenkonzo.

Ngesikhathi sempilo yenkonzo yamapayipi e-PVC, ukuvezwa kwezinto zangaphandle njengokukhanya kwelanga, ukuguquguquka kwamazinga okushisa, amakhemikhali, njll. Sizosheshisa ukonakaliswa kwezinto ze-PVC. Abaqinisi bokushisa kwe-PVC badlala indima ebalulekile ekuvikeleni amapayipi kulezi zinto ezonakalisayo, baqinisekisa ukusebenza kwabo kwesikhathi eside kanye nokwethembeka.

Ukusetshenziswa kwe-PVC Heat Stuvilizerger kubalulekile ukuze ulondoloze ikhwalithi nokusebenza kwamapayipi e-PVC. Lezi zibalo zivikela impahla ye-PVC ekuwohlokeni okushisayo futhi kuqinisekiswe ukuthi ipayipi ligcina izakhiwo zalo emishini, ukuqina kombala kanye nobuqotho obukhulu. Njengobuchwepheshe bezinkomishini kuthuthuka, manje sekunezindlela ezahlukahlukene zokuhlangabezana nezidingo ezithile zezinhlelo zokusebenza zePVC ehlukile. Njengoba isidingo samapayipi asezingeni eliphakeme futhi ahlala isikhathi eside e-PVC aqhubeka nokukhula, ukubaluleka kwama-PVC okushisa okugcina embonini yePVC angeke aqedwe ngokweqile.
