High density Polyethylene Txhaj Moulding Qib
HDPE yog ib qho crystalline uas tsis yog-polar thermoplastic resin ua los ntawm copolymerization ntawm ethylene thiab ib qho me me ntawm α-olefin monomer.HDPE yog synthesized nyob rau hauv qis siab thiab yog li ntawd kuj hu ua low-pressure polyethylene.HDPE feem ntau yog cov qauv linear molecular thiab muaj me ntsis branching.Nws muaj qib siab ntawm crystallization thiab siab ceev.Nws tuaj yeem tiv taus qhov kub thiab txias thiab muaj qhov zoo rigidity thiab mechanical zog thiab anti-chemical corrosion.
HDPE txhaj tshuaj molding qib muaj qhov sib npaug zoo ntawm rigidity thiab toughness, zoo cuam tshuam tsis kam thiab zoo heev ntawm qhov kub thiab txias tsis kam thiab zoo ib puag ncig kev ntxhov siab tawg tiv thaiv.Cov cob muaj zoo rigidity thiab abrasion kuj, thiab zoo processability.
Cov resin yuav tsum tau muab khaws cia rau hauv ib qho chaw qhuav, qhuav warehouse thiab deb ntawm hluav taws thiab tshav ntuj ncaj qha.Nws yuav tsum tsis txhob muab tso rau hauv qhov qhib cua.Thaum lub sij hawm kev thauj mus los, cov khoom yuav tsum tsis txhob raug tshav ntuj los yog nag thiab yuav tsum tsis txhob raug thauj nrog xuab zeb, av, seem hlau, thee lossis iav.Kev thauj mus los ua ke nrog cov tshuaj lom, corrosive thiab flammable yog nruj me ntsis txwv.
Daim ntawv thov
HDPE txhaj- molding qib yog siv los ua cov ntim khoom siv rov siv dua, xws li cov thawv npias, cov dej haus, cov khoom noj, cov zaub zaub thiab cov qe qe thiab tseem tuaj yeem siv los ua cov tais yas, cov thawv ntim khoom, cov khoom siv hauv tsev, cov khoom siv niaj hnub thiab nyias- phab ntsa ntim khoom noj.Nws tseem tuaj yeem siv rau hauv kev tsim cov khoom siv-siv thoob, khib nyiab khib nyiab thiab cov khoom ua si.Los ntawm cov txheej txheem extrusion thiab compression molding thiab txhaj tshuaj molding, nws tuaj yeem siv los tsim lub kaus mom ntawm cov dej huv, dej ntxhia, dej tshuaj yej thiab kua txiv hmab txiv ntoo.
