I-Single Plastic Screw Barel Working Principles

Ukunyibilika kunye ne-Homogenization Mechanism

A iplastiki enye jija umphandaisebenzisa indibaniselwano yenkqubo yomatshini kunye ne-thermal ukunyibilika kunye nokuxuba izinto zeplastiki. Isikrufu sijikeleza ngaphakathi kwibhere, sityhalela iipellet zeplastiki phambili. Njengoko iipellet zihamba, kukho izinto ezininzi ezibalulekileyo ezenzekayo:

• Ukucheba koomatshini kunye nokukhuhlana phakathi kweenqwelomoya ezijijwayo kunye neendonga zemibhobho zivelisa ubushushu. Obu bushushu bunyusa ubushushu beplastiki.
• Izifudumezi zangaphandle kwi-barrel zongeza ubushushu obuninzi, ziqinisekisa ukuba iplastiki iyancibilika ngokulinganayo.
• Iindawo yoxinzelelo ngaphakathi komgqomokunciphisa indawo, eyandisa zombini uxinzelelo kunye nobushushu. Olu tshintsho kancinane lunyibilikisa ipholima ukusuka kokuqinileyo ukuya kwimeko enyibilike ngokupheleleyo.
• Isikrufu esijikelezayo sixuba iplastiki etyhidiweyo kakuhle. Esi senzo sokuxuba siqinisekisa ukuba izinto eziphathekayo ziba ne-homogeneous, kunye neempawu ezihambelanayo kulo lonke.
• Izongezo, ezifana ne-colorants okanye i-stabilizers, zinokudibaniswa ngeli nqanaba. Isenzo sokuxuba isikrufu sinceda ukusasaza ezi zongezo ngokulinganayo.
• Ummandla wokulinganisa ekupheleni kwe-screw ugcina uxinzelelo oluzinzileyo kunye nokuhamba, ulungiselela izinto eziphathekayo kwisigaba esilandelayo sokucubungula.

Qaphela: Ukunyibilika okufanayo kunye nokuxuba kubalulekile ekuveliseni iimveliso zeplastiki ezinamandla athembekileyo, umbala, kunye nokugqitywa komphezulu.

UThutho lweMathiriyeli kunye noLawulo loxinzelelo
