Umahluko weNtsebenzo phakathi kweplate ye-POM kunye neplate

Iplate iluhlobo lwe-thermoplastic i-thermoplastic i-therstaritity ephezulu kunye ne-non-chiefy. Inkangeleko ye-PE ye-PA i-SILY Mhlophe, kwaye iyahamba ukuya kwinqanaba elithile kwicandelo elincinci.

Iplate ichaphazela ukumelana kakhulu kwiikhemikhali ezininzi zasekhaya nezamashishini. Iindidi ezithile zeekhemikhali zinokubangela ukuntywila kweekhemikhali, ezinje ngee-oxidants zekhemithi (i-witric acid), i-hidrocarbons (i-hidrocarbons (i-charbone) kunye ne-hydrocarbons (i-carbon). I-polymer ayifumani mtyumbo kwaye inamanzi amdaka omninzi, kwaye inokusetyenziselwa ukulungiselela ukupakisha. I-PE ineepropathi ezifanelekileyo zombane, ngakumbi amandla aphezulu kaDirectoric, owenza ilungele kakhulu iingcingo kunye neentambo. Inqanaba eliphakathi ukuya kwi-Molecular Counts Momeler Countral inamabanga aphezulu okunyangeka, nakwiqondo lobushushu legumbi kunye - 40f iqondo lobushushu elisezantsi. Iimpawu ezizodwa ze-PED yamabanga ahlukeneyo yindibaniselwano efanelekileyo yezinto ezine ezisisiseko: Ukuxinana, ubunzima bemolekyuli, ukusasazwa kwesisindo kunye nokongezwa kwezihloko. I-catalysts ezahlukeneyo isetyenziselwa ukuvelisa ii-polymers ezenzelwe ngokwezifiso ezinepropathi ekhethekileyo. Ezi zinto ziguquguqukayo zidityanisiwe ukuba zivelise amabakala e-PE ngeenjongo zaza ezahlukeneyo kwaye zifezekise eyona ibhalansi yentsebenzo. Inozinzo oluhle lweekhemikhali kwaye linokuxhathisa ukhukuliseko lwe-acid, ialkali, isisombululo sezinto eziphilayo kunye namanzi ashushu. I-incumation yombane ilungile.

Indawo yokunyibilika yephepha le-PE imalunga ne-130 ℃, kunye nokuxinana kwesihlobo yi-0.941-0.960. Inokuchasana nobushushu obuhle kunye nokungaxhathisi kubanda, uzinzo lweekhemikhali, ubungqola obuphakathi kunye nobuchule, kunye namandla amahle ngoomatshini. Iipropathi zeDiectoric kunye neNkxaso-mali yokuSebenza yokuNgela kwiNdawo yokuNgela kwiNdawo yokuNgcaca yendalo ilungele. Ubushushu obunyibiliza bususela kwi-220 ℃ ukuya kwi-260 ℃. Ngezixhobo ezinobukhulu obukhulu kwimolekyuli, uluhlu lobushushu lokunyibilika lucetyiswa ukuba lube phakathi kwe-200 ukuya kwi-250 ℃.

Iplate ye-POM, eyaziwa ngokuba yiprinte ye-delrin, ikhutshiwe ngamasuntswana eplastiki kwi-POM kwiqondo eliphezulu, ngokusebenzisa ipleyiti yokufelwa. Yiplastiki yobunjineli be-thermoplastic ngokunyibilikisi okuphezulu kunye ne-crystallies ephezulu. Ngenxa yeempawu ezintle zeplate ye-POM, ilungele kakhulu umatshini kwizilolo ezizenzekelayo, ngakumbi ukwenza iinxalenye ezichanekileyo.

Iplate ye-POM iluhlobo lwe-copolymer ngaphandle kwekhonkco lecala, uxinzelelo oluphezulu kunye ne-crystallies ephezulu. Inezixhobo ezigqibeleleyo ezigqibeleleyo.

Iplate ye-POM iluhlobo lwezinto ezinzima nezihlanganisiweyo zendawo egudileyo kunye ne-luster. Imnyama okanye imhlophe kwaye inokusetyenziselwa ixesha elide kuluhlu lobushushu lwe-40 ukuya kwi-106 deger ℃. Ukunganyangekala kwawo kunye nokuzimela kwazo kuphakamile kuneplasitiki yobunjineli. Ikwanokuchasana neoyile elungileyo kunye nokuxhathisa kwepetroli. I-Acid-Ukunganyangeki kakhulu, i-alkali-enganyangekiyo kunye nenyanga ye-Ultraviolet ye-Ultraviolet ye-radiant.

I-POM yiplastiki ye-crystalline enendawo yokunyibilika. Nje ukuba inqaku lokunyibilika lifikelele, ukunyibilika i-vissosity inciphisa ngokukhawuleza. Xa iqondo lobushushu lidlula umda othile okanye inyibilike ishushu ixesha elide, iya kubangela ukungavisisani.
