I-1) I-PBT ine-hygroscopicity ephansi, kodwa izwela kakhulu kumswakama emazingeni okushisa aphezulu. Izokwehlisa ama-molecule e-PBT ngesikhathiukubumbainqubo, yenza mnyama umbala futhi ikhiqize amachashazi ebusweni, ngakho-ke kufanele yomiswe ngokuvamile.
2) I-PBT melt ine-fluidity enhle kakhulu, ngakho-ke kulula ukwenza imikhiqizo enezindonga ezincane, ezimise okuyinkimbinkimbi, kodwa naka isikhunta esibenyezelayo kanye nokuconsa umlomo.
3) I-PBT inephuzu lokuncibilika elisobala. Lapho izinga lokushisa likhuphuka ngaphezu kwendawo yokuncibilika, i-fluidity izokhula ngokuzumayo, ngakho-ke kufanele kuqashelwe kuyo.
I-4) I-PBT inobubanzi obuncane bokucubungula bokubumba, icwebezela ngokushesha lapho ipholisa, kanye ne-fluidity enhle, efaneleka ngokukhethekile umjovo osheshayo.
5) I-PBT inezinga elikhudlwana lokushwabana kanye nobubanzi bokuncipha, futhi umehluko wesilinganiso sokuncipha ezindaweni ezihlukene usobala kakhulu kunamanye amapulasitiki.
I-6) I-PBT izwela kakhulu ekuphenduleni kwamanotshi namakhona acijile. Ukugxiliswa kwengcindezi kungenzeka kwenzeke kulezi zindawo, okunciphisa kakhulu umthamo wokuthwala umthwalo, futhi kujwayele ukugqashuka lapho kuphoqelelwe noma kube nomthelela. Ngakho-ke, lokhu kufanele kunakwe lapho uklama izingxenye zepulasitiki. Wonke amakhona, ikakhulukazi amakhona angaphakathi, kufanele asebenzise ukuguqulwa kwe-arc ngangokunokwenzeka.
I-7) Izinga lokwelulwa kwe-PBT ehlanzekile lingafinyelela ku-200%, ngakho-ke imikhiqizo ene-depressions encane ingaphoqwa ngaphandle kwesikhunta. Kodwa-ke, ngemuva kokugcwalisa nge-fiber yengilazi noma i-filler, ukuphakama kwayo kuncishiswe kakhulu, futhi uma kukhona ukucindezeleka emkhiqizweni, ukudilizwa okuphoqelelwe akukwazi ukuqaliswa.
I-8) Umgijimi wesikhunta se-PBT kufanele abe mfushane futhi aminyene uma kungenzeka, futhi umgijimi oyindilinga uzoba nomphumela omuhle kakhulu. Ngokuvamile, kokubili i-PBT eguquliwe nengashintshiwe ingasetshenziswa nabagijimi abavamile, kodwa i-PBT ye-glass fiber-reinforced ingaba nemiphumela emihle kuphela lapho kusetshenziswa ukubumba komgijimi oshisayo.
9) Isango lephoyinti kanye nesango elifihlekile linomphumela omkhulu wokugunda, onganciphisa i-viscosity ebonakalayo ye-PBT melt, ehambisana nokubunjwa. Yisango elisetshenziswa njalo. Ububanzi besango kufanele bube bukhulu.
I-10) Isango lingcono kakhulu ukubhekana nomgodi oyinhloko noma umgogodla, ukuze ugweme ukufafaza futhi unciphise ukugcwaliswa kokuncibilika lapho kugeleza emgodini. Uma kungenjalo, umkhiqizo uthambekele ekubeni nokukhubazeka okungaphezulu futhi uwohloza ukusebenza.
