Ziziphi iindlela zokusebenzisa kunye nokhuseleko lomlawuli we-PVC foaming

Ukusetyenziswa komlawuli we-PVC foaming:

Ukufutha kwezinto zePVC kukwenza usasazo lweemolekyuli zePVC lufane ngakumbi. Yenza umgangatho weemveliso zePVC ube ngowokuthe ngqo. Iphepha lePVC elifutha yiPVC foaming regulator linesakhiwo esihle kakhulu esizimeleyo. Ngamanye amaxesha, ngelixa sisebenzisa iPVC foaming regulator, sisebenzisa nezinye ii-foaming accelerators. Ii-foaming accelerators ziquka ii-metal oxides ezifana ne-zinc oxide kunye ne-lead oxide, ii-organic acid salts ezifana ne-zinc stearate, kunye ne-urea derivatives.

Iingenelo zomlawuli we-PVC foaming:

Umlawuli we-PVC foaming unazo zonke iimpawu zezixhobo zokulungisa i-PVC, kwaye ubunzima be-molecular buphezulu kunobo bezixhobo zokulungisa i-PVC. Ukongeza ubungakanani obufanelekileyo bomlawuli we-PVC foaming ngexesha lokucubungula iimveliso ze-PVC kunokuphucula amandla okunyibilika kwaye kuthintele i-fu.ukwenziwa kwamaqamza. Kwangaxeshanye, inokuba nefuthe elihle lokwenza iplastiki ibe nkulu. Injongo kukuqinisekisa ukuba ukunyibilika kuthambile.

Amanyathelo okusebenzisa i-PVC foaming regulator:

Xa usebenzisa ii-PVC foam modifiers, kubalulekile ukuba unikele ingqalelo kwiimveliso zePVC ezinamaqondo ahlukeneyo e-polymerization kwaye ukhethe ii-foam modifiers ezahlukeneyo. Iimveliso zeplastiki ze-foam ziquka iibhodi ze-foam, iibhodi ezixineneyo ze-foam, iibhodi ze-foam ezibhityileyo, iibhodi ze-foam zeplastiki zomthi, iibhodi ze-foam zeplastiki ezikhokelayo, njl. Njengoko izongezo ze-PVC foam nazo zizinto ze-acrylic ezineempawu zoncedo lokucubungula, kufuneka kuqwalaselwe ibhalansi yokuthambisa yangaphakathi neyangaphandle yefomyula xa uyisebenzisa.

Amanqaku aphambili olawulo lwenkqubo yokufutha nge-PVC:

Ukubumba i-foam yeplastiki kwahlulwe ngeendlela ezintathu: ukwenziwa kwe-bubble core, ukwandiswa kwe-bubble core, kunye nokuqina komzimba we-foam. Kwii-foam sheets ze-PVC ezinee-agents ze-foam ezongezelelweyo, ukwandiswa kwee-bubble nuclei kunempembelelo ebalulekileyo kumgangatho we-foam sheet. I-PVC yeyee-molecules ze-straight chain ezinee-molecular chains ezimfutshane kunye namandla aphantsi okunyibilika. Ngexesha lenkqubo yokwandiswa kwe-bubble core ibe yi-bubbles, ukunyibilika akwanelanga ukugubungela ama-bubbles, kwaye igesi ithambekele ekuphuphumeni kwaye idibane ibe ngama-bubbles amakhulu, okunciphisa umgangatho wemveliso yee-foam sheets.
