Unolwazi olungakanani malunga nabalawuli be-PVC foaming

1, Indlela yeFoam:

Injongo yokongeza iipolymers ezinobunzima obukhulu kakhulu kwiimveliso ze-foam ze-PVC kukukhuthaza ukwenziwa kwe-PVC ibe yiplastiki; Okwesibini kukuphucula amandla okunyibilika kwezinto ze-foam ze-PVC, ukuthintela ukudibana kwamaqamza, kunye nokufumana iimveliso ezine-foam efanayo; Okwesithathu kukuqinisekisa ukuba i-melt inobumanzi obuhle, ukuze kufumaneke iimveliso ezinembonakalo entle. Ngenxa yokwahluka kweemveliso, izixhobo, iinkqubo, izinto ezikrwada, kunye neenkqubo zokuthambisa ezisetyenziswa ngabenzi beemveliso ze-foam ezahlukeneyo, siye saphuhlisa abalawuli be-foam abanobuchule obahlukeneyo ukuhlangabezana neemfuno ezahlukeneyo zabasebenzisi.

1. Inkcazo yezinto ezisetyenziswa kwiFoam

Iplastiki enefoam, eyaziwa ngokuba yiplastiki enefoam, yinto edityanisiweyo eneplastiki njengeyona nto iphambili kunye nenani elikhulu lamaqamza, ekunokuthiwa azaliswe yigesi.

2. Uhlu lwezixhobo zeFoam Sheet

Ngokwemilinganiselo eyahlukeneyo yokufutha, inokwahlulwahlulwa ibe yi-foam ephezulu kunye ne-foam ephantsi, kwaye ngokwendlela umzimba we-foam oqinileyo ngayo, inokwahlulwahlulwa ibe yi-foam eqinileyo, eqinileyo nethambileyo. Ngokwesakhiwo seseli, inokwahlulwa ibe yi-closed cell foams kunye ne-open cell foams. Iphepha le-PVC foam elisetyenziswa rhoqo lelephepha le-hard closed cell low foam sheet.

3. Ukusetyenziswa kwamaphepha e-PVC foam

Iiphepha ze-PVC foam zinezibonelelo ezifana nokumelana nokugqwala kweekhemikhali, ukumelana nemozulu, kunye nokungatshisi ilangabi, kwaye zisetyenziswa kakhulu kwiinkalo ezahlukeneyo, kubandakanya iiphaneli zokubonisa, iimpawu, iibhodi zentengiso, izahlulo, iibhodi zokwakha, iibhodi zefenitshala, njl.

4. Izinto eziphambili zokuvavanya umgangatho weeshiti zefoam

Kwizinto ezikhupha igwebu, ubungakanani kunye nokufana kweembobo zegwebu zezona zinto zibalulekileyo ezichaphazela umgangatho wephepha. Kwiphepha legwebu elinobukhulu obuphantsi, iimbobo zegwebu zincinci kwaye ziyafana, iphepha legwebu linokuqina okuhle, amandla aphezulu, kunye nomgangatho olungileyo womphezulu. Ngokwembono yokunciphisa uxinano lweephepha zegwebu, ziimbobo zegwebu ezincinci nezifanayo kuphela ezinokuthi zinciphise uxinano ngakumbi, ngelixa igwebu elikhulu nelisasazekileyo kunzima ukulinciphisa ngakumbi uxinano.
