Iindaba

Kwiminyaka yakutshanje, kukho inkqubo ye-screw ye-screw ye-screw Seker isekwe kwimarike njengenye indlela yokutsala i-screw yokwahlulahlula i-scrives enye ngenkqubo yokomisa kwangaphambili. .

Kodwa sicinga ukuba kubalulekile ukuba nenkqubo yokomisa ngaphambi kokusomisa nangawo usebenzisa i-halti-screw deprucler. Kuba:

I-1) Isikrelemnqa amaqela aphesheya ukuba bonke banayo i-vacus entsokothileyo ye-vacuum yokufakelwa i-vacuus efakiweyo kwifuthe lokuthintela i-hydrolysis yokuthintela i-hydrolysis yokufakwa ngenxa yenkqubo yokomisa. Ihlala iluhlobo olo olwenziwe ngemeko yoMgangatho:

Ubuninzi bokutya okuvunyiweyo kufuneka kungabikho ngaphezulu kwe-3000 PPM (0.3%)

Ngapha koko, iiflethi zebhotile zibonisa umahluko kubunyulu, ubungakanani bentsumpa, ubungakanani be-paricle yokusasazwa kunye nobungqingqwa - ngakumbi ekufumeni. Iiflethi zabathengi emva komthengi zivumela ukugcinwa kwe-5,000 ye-PPM yoMsulwa kwimveliso kwaye ugcine amaxesha amaninzi ngelishwa. Kwamanye amazwe, ukuntywila ukutya kungafikelela kwi-14,000 i-PPM iqhubekwe kwingxowa enkulu.

Zombini inqanaba eligqibeleleyo lomxholo wamanzi kunye nohluko wayo, ongenakuthintelwa, ngaba umngeni wokwenene kwisikrweqe esikhulu se-screw kunye nomxholo ofanelekileyo wokudinwa. Oku kuphuka rhoqo ekwenzeni ukuguquguquka okuguqukayo, okubonakalayo kuxinzelelo lwezinto eziguqukayo. i-resin, kunye nemali esuswe ngexesha lokuphumla

2) I-PET i-hygroscopic kwaye ifumana ukufuma kwimozulu. Isixa esincinci somswakama siya kukufuma kwe-hydrolyze i-hydrolyze isigaba sokunyibilika, ukunciphisa ubunzima bemolekyuli. Isilwanyana esifuywayo kufuneka some ngaphambi nje kokuqhubekiswa, kwaye isilwanyana sase-Amorphous sifuna ukungcungcutheka ngaphambi kokuba sonyuke ukuze amasuntswana ayinamathele ndawonye.

I-Hydrolysis inokwenzeka ngenxa yokufuma kwaye oku kuhlala kubonakala njengonciphiso kwi-IV (i-vissinic vissity) yemveliso. Isilwanyana sasekhaya "se-semi-rirstalline". Xa i-IV incitshisiwe, iibhotile ziyibhulethi ngakumbi kwaye zithanda ukusilela "kwisango" (indawo yesango) ngexesha lokubetha kunye nokuzalisa.

Kwilizwe layo "le-crystalline" line-crystalline kunye ne-amorfous yesahlulo kwisakhiwo sayo semolekyuli. Inxalenye ye-crystalline ikhula apho iimolekyuli zingazilungelelanisa khona kwindawo ye-compact yecompact. Kwimimandla engeyiyo i-rystalline Iimolekyuli zikwilungiselelo elingaqhelekanga. Ngokunyanzela ukuba i-crystallies yakho iphezulu, ngaphambi kokuqhubekiswa, isiphumo siya kuba yinto eninzi ngakumbi kunye nemveliso esemgangathweni ephezulu.

I-ODE yenza ukuba i-Ird Dearing Drum Systems yenze le misebenzi isebenza ngendlela efanelekileyo amandla afanelekileyo. Special designed shortwave Infrared radiation stimulates the molecular heat fluctuation in the dry material directly without taking the rather inefficient intermediate step of using heated air. Indlela eshushu kakhulu kunye namaxesha owomileyo incitshisiwe kuluhlu lwemizuzu e-8.5 kuphela ukuya kuthi ga kwi-20 imizuzu kuxhomekeke kwisicelo esithile, ngelixa iiyure ezininzi kufuneka zibalwe kwiinkqubo ezinobushushu ezishushu okanye iinkqubo zomoya.

Ukoyiswa kwe-infrared kunokuphucula kakhulu ukusebenza kwe-Twin-Screw Serser kuba kunciphisa ukonakaliswa kwexabiso le-IV kunye nokuphucula kakhulu uzinzo kuyo yonke inkqubo.
