Iimbangela ze-Brittleness kwi-PET Sheets
Izinto ezibangela ubumdaka kumaphepha e-PET zintsonkothile kwaye zinokubalelwa kwizinto ezininzi eziphambili:
1. Ukunyangwa kokushisa okugqithisileyo Ngethuba lokuveliswa kwamaphepha e-PET, unyango olushushu luyafuneka. Nangona kunjalo, ukuba unyango lobushushu lugqithise, lunokukhokelela kwiqondo eliphezulu kakhulu le-crystallization, ebangela ukuba iphepha libe lukhuni kwaye lithande ukuqhekeka.
2. Ukuthotywa kwezongezo Izongezo ezahlukahlukeneyo ezifana neeplasticizers, stabilizers, colour masterbatches zifakwe kumaphepha ePET. Ukuthotywa kwezi zongezo kunokukhokelela ekulahlekelweni kobunzima bokuqala bephepha, okwenza kube buthathaka ngakumbi. Ukongeza, izinto ezinje ngokugqithisileyo, ukusetyenziswa ngaphantsi, okanye ulandelelwano olungafanelekanga lwezongezo zinokuchaphazela umgangatho wamaphepha e-PET.
3. IiMeko zokuGcina ezingafanelekanga Indawo yokugcina ichaphazela kakhulu umgangatho wamaphepha e-PET. Ukuba zigcinwe kwiimeko ezinobushushu obuphezulu okanye ukufuma, amaphepha e-PET anokuthi afumane i-oxidation okanye i-decomposition reactions, ekhokelela kwi-brittleness.
4. Imiba yeNkqubo yoMveliso Ukuphathwa ngendlela engafanelekanga ngexesha lenkqubo yokuvelisa nako kunokuchaphazela umgangatho wamaphepha e-PET. Izinto ezifana nenkqubo ye-extrusion, ulawulo lokupholisa, kunye nokulungiswa koxinzelelo kunokuguqula isakhiwo sangaphakathi sephepha, okubangela ukulahlekelwa kweempawu zoomatshini kunye nokunyuka kwe-brittleness.
Amanyathelo oThintelo lwe-PET Sheet Brittleness
Ukuthintela ukonakala kumaphepha ePET, amanyathelo aliqela anokuthathwa:
1. Lawula ubushushu boNyango loNyango Ngexesha lemveliso, kubalulekile ukuba ulawule ngononophelo ubushushu bonyango lobushushu kunye nobude bexesha lokuthintela i-crystallization egqithisileyo, enokukhokelela kwi-brittleness.
2. Ukongezwa okuLungileyo kwezoNgezelelweyo kudlala indima ebalulekileyo kumgangatho wamaphepha ePET. Kubalulekile ukukhetha kunye nokuzongeza ngokufanelekileyo ngokusekelwe kwiimfuno zangempela. Ukongeza, uvavanyo lwarhoqo kufuneka lwenziwe ukujonga umgangatho wezongezo ukunqanda ukuthotywa okunokuthi kuchaphazele ukuqina kwephepha.
3. Ukulawulwa kweeMeko zokuGcinwa kwamaPhepha e-PET kufuneka agcinwe kwindawo eyomileyo, enomoya opholileyo, kunye neendawo ezinobungqina bomswakama, ukuphepha ukubonakaliswa kwamaqondo aphezulu kunye nomswakama. Kumaphepha agcinwe ixesha elide, iinkqubo zokomisa zingasetyenziswa ukunciphisa umthamo wokufuma.
4. Ukuqinisekisa iMisebenzi yoMveliso eLungileyo Ngexesha lokuvelisa, abaqhubi kufuneka balandele iinkqubo ezifanelekileyo zokuthintela imiba ebangelwa yinkqubo ye-extrusion, ulawulo lokupholisa, okanye ukulungiswa koxinzelelo olunokuchaphazela isakhiwo sangaphakathi kunye nokusebenza komatshini wee-PET sheets.
5. Amaphepha e-PET zizinto zokupakisha ezisebenza kakhulu, kodwa i-brittleness yinto eqhelekileyo kwizicelo eziphathekayo. Ukuze ugweme i-brittleness, kufuneka kunikwe ingqalelo ngononophelo kulawulo lwemveliso kunye neeparamitha zokusetyenziswa, ezifana nonyango lobushushu, ukhetho olongezelelweyo kunye nedosi, kunye neemeko zokugcina. Ngokulawula ngokungqongqo le miba, kunokwenzeka ukuvelisa amaphepha e-PET kunye nokusebenza okuzinzile.
Oku Ukuzenzekela kwiZitishi eziNtathu zePlastiki zokuThermoforming ngoxinzelelo lwePlastiki yenzelwe ukuveliswa kwezikhongozeli zeplastiki ezahlukeneyo (itreyi yeqanda, isikhongozeli seziqhamo, isikhongozeli sokutya, izikhongozeli zepakethe, njl.njl) ezinamashiti ashushu, njenge I-PS, i-PET, i-HIPS, i-PP, i-PLA, njl
Umenzi ochwephesha woomatshini be-thermoforming.
