Ungathini ukushisa ipayipi ye-PPR?

1, ukuvumelanisa kwezinsiza kusho ukuthi kumele kube khona. Ukushisa kwe-PP-R hot melt kusho ukuthi: 253C-274 °. Uma isimo seliphansi kwe-253, ipayipi kanye nezinsiza zepayipi zikhona kuphela isimo esincane sengqondo yezinsiza, uma zisivumelene, ubukhulu bokuvumelanisa akubalulekile, okuyinto esikhathazekile kakhulu, uma isimo seliphezulu kwe-274 ° C, izintombi zesimo sezinsiza zisitshengiswa ngokwezinkathi eziningi, zikwenza i-PP-R isakhiwe isimitha esincane, okwamanje, isixazululo sizokwenza isikhala esiphansi, okwamanje uma indlela yokuhlukaniswa yepayipi ikhona kusukela kubanjwe kanye nezinsiza, izinto eziningi ezikhona.
2, Isikhathi sokuvumelanisa kumele kube kude. Ukuphakama kwezikhathi zokuvumelanisa kusho ukuthi kumele kube nokubaluleka kakhulu kwezinhlelo zokushisa ngokushisa. Izinhlelo zokushisa zisebenza ngokuthi zikhomba isimo sokushisa emva kokushisa kubalulekile, ikakhulukazi ngoLwesibili, isitshengiswa sengqondo, futhi ngaphandle kwezinkinga, ukushisa kwazo kanye nezinsiza zazo kusho ukuthi kuzoshisa isimo ngokwesibindi, okuyinto esikhathazekile kakhulu, uma indlela yokuhlukaniswa yepayipi ikhona kusukela kubanjwe kanye nezinsiza zazo, izinto eziningi ezikhona.
