Iitshiphu zePolyester eziNyibilikayo zaManzi eziManzi eziManzi kunye noLudaka
Ukunamathela okugqwesileyo;ine-molecular structure efana ne-polyester, kwaye ine-adhesion egqwesileyo kunye ne-polyester.Ukubambelela nge-polyester kungcono kakhulu kune-PVA, i-acrylate, isitashi esilungisiweyo kunye nezinye i-slurries.
Ukunyibilika kakuhle kwamanzi;Inyibilika ngokulula kumanzi ashushu ngaphezulu kwe-80℃, akukho mvula, akukho kulusu, ukuhambelana kakuhle nestatshi, iPVA, i-acrylic slurry, akukho mvula, akukho stratification.
I-viscosity ephantsi kwaye izinzile;iyaziqhelanisa ne (ukungaguquguquki okuphezulu, uxinzelelo oluphezulu, i-viscosity ephantsi) inkqubo yokulinganisa, ukungena okunamandla, kulula ukufumana ukungena okulungileyo, ukuhlangana kwefayibha, ukunamathela kweenwele.
Ifilimu yobungakanani iqinile;yomelele, igudileyo kwaye iyabonakala, yophukile ngokulinganayo xa iqhekeka, kwaye umsonto ugudile.Ukuvulwa kwe-loom kucacile, okunciphisa ngokufanelekileyo izinga lokuqhawula intambo ye-warp kunye nokuphucula ukusebenza kakuhle kwe-loom.
Ukutshintsha iPVA kunokunciphisa iindleko;I-PVA inokutshintshwa yi-1: 2, enokunciphisa kakhulu ixabiso le-slurry kwindawo yokuqinisekisa ukuluka.
Imeko-bume;ingaba yi-alcoholsis, i-hydrolysis, i-alkali degradation, i-photodegradation kunye ne-microbial degradation.Akunjalo kuphela ukusebenza kokuthotywa kwe-PVA, kodwa kwakhona i-dosage yi-1/2 ye-PVA kuphela, enokunciphisa iindleko zokunyanga kwamanzi amdaka.Ludaka oluhambelana nokusingqongileyo.

Ifomula: Ngokwesiseko sefomula ekhoyo, umthamo opheleleyo oqinileyo uhlala ungaguquki, kwaye i-1kg ye-polyester slurry enyibilikayo emanzini isetyenziselwa ukutshintsha i-2kg ye-PVA.Inxalenye engonelanga yongezwa ngestatshi okanye isitashi esilungisiweyo, kwaye isixa esifanelekileyo searhente yeoli kunye nearhente ye-antistatic yongezwa ukuze kuqinisekiswe uqikelelo lobungakanani bezinga (elona zinga lokulinganisa liya kuba sezantsi kancinci).
Ubungakanani: beka ubungakanani obufanelekileyo bamanzi kwibhakethi yokulinganisa, vula ukuxuba, qala ubeke kwistatshi, emva koko ubeke kwi-polyester enyibilikayo eludaka, ushukumise ngokupheleleyo, emva koko unyuse ubushushu bube ngaphezulu kwe-95 ℃, emva koko uvule ivalve encinci yomoya ukuze ubilise ngaphezu kwemizuzu engama-30, uze udibanise ioli, i-agent antistatic okanye i-slurry engamanzi, ubilise kwaye udibanise kakuhle, uze uyisebenzise emva kokumisela umthamo kunye ne-viscosity.
Sebenzisa phantsi kwesikhokelo seengcali zobuchwephesha.
Kwifomula yodaka, udaka oluncedisayo oluqulethe isinyithi esine-bivalent okanye iityuwa zetsimbi enzima kufuneka luthintelwe kangangoko kunokwenzeka, kwaye amanzi anobulukhuni obuphezulu kufuneka aphetshwe kangangoko kunokwenzeka.Amanzi anobulukhuni obuphezulu kakhulu kufuneka athanjiswe phambi kokuba asetyenziswe.Musa ukusebenzisa i-NaOH njenge-arhente yokubola ngexesha lokuxuba oludaka.Ixabiso le-PH le-slurry kufuneka libe phakathi kwe-6 kunye ne-7.
