I-1) I-PBT ine-hygroscopicity ephantsi, kodwa ivakalelwa ngakumbi kumswakama kumaqondo aphezulu. Iya kuthoba iamolekyuli ze-PBT ngexeshaukubumbainkqubo, mnyama umbala kwaye uvelise amabala phezu komhlaba, ngoko kufuneka ngokuqhelekileyo yomiswe.
2) I-PBT inyibilika ine-fluid egqwesileyo, ngoko kulula ukwenza iimveliso ezinodonga olucekethekileyo, ezinobumba obuntsonkothileyo, kodwa qaphela ukudanyaza kokungunda kunye ne-nozzle evuzayo.
I-3) I-PBT inendawo yokunyibilika ebonakalayo. Xa iqondo lokushisa liphakama ngaphezu kwendawo yokunyibilika, i-fluidity iya kwanda ngokukhawuleza, ngoko kufuneka kuhlawulwe ingqalelo kuyo.
I-4) I-PBT inoluhlu olumxinwa lokubumba, i-crystallizes ngokukhawuleza xa ipholisa, kunye ne-fluidity enhle, efanelekileyo kakhulu kwinaliti ekhawulezayo.
I-5) I-PBT inomlinganiselo omkhulu wokunciphisa kunye noluhlu lwe-shrinkage, kwaye ukuhlukana kwezinga lokunciphisa kwiindlela ezahlukeneyo kubonakala ngakumbi kunezinye iiplastiki.
I-6) I-PBT inomdla kakhulu kwimpendulo yeenotshi kunye neekona ezibukhali. Uxinzelelo loxinzelelo lunokwenzeka kwezi zikhundla, nto leyo inciphisa kakhulu umthamo wokuthwala umthwalo, kwaye ithanda ukugqabhuka xa iphantsi kokunyanzelwa okanye impembelelo. Ngoko ke, oku kufuneka kuthathelwe ingqalelo xa uyila iinxalenye zeplastiki. Zonke iikona, ngokukodwa iikona zangaphakathi, kufuneka zisebenzise iinguqu ze-arc kangangoko kunokwenzeka.
I-7) Isantya sokwandisa i-PBT ecocekileyo inokufikelela kwi-200%, ngoko ke iimveliso ezinoxinzelelo oluncinci zinokunyanzeliswa ngaphandle kwesikhunta. Nangona kunjalo, emva kokuzaliswa ngefiber yeglasi okanye i-fiber, i-elongation yayo iyancipha kakhulu, kwaye ukuba kukho ukudakumba kwimveliso, ukuchithwa okunyanzeliswayo akukwazi ukuphunyezwa.
I-8) Umgijimi we-PBT mold kufuneka abe mfutshane kwaye atyebe ukuba kunokwenzeka, kwaye umgijimi ojikelezayo uya kuba nefuthe elihle. Ngokubanzi, zombini i-PBT eguquliweyo kwaye engaguquguqukiyo ingasetyenziswa kunye nabagijimi abaqhelekileyo, kodwa i-PBT ye-glass fiber-reinforced inokuba neziphumo ezilungileyo kuphela xa kusetyenziswa ukubunjwa komgijimi oshushu.
9) Isango lendawo kunye nesango elifihliweyo linempembelelo enkulu yokucheba, enokunciphisa i-viscosity ebonakalayo ye-PBT inyibilika, ehambelana nokubumba. Lisango elisetyenziswa rhoqo. Idayamitha yesango kufuneka ibe nkulu.
I-10) Isango lilungele ukujongana ne-core cavity okanye i-core, ukwenzela ukuba ugweme ukutshiza kunye nokunciphisa ukuzaliswa kwe-melt xa ugeleza kwi-cavity. Ngaphandle koko, imveliso ixhomekeke kwiziphene zomhlaba kwaye iyancipha ukusebenza.
