Phetoho ea tataiso ea PBT
1. Phetoho ea ntlafatso
Ho PBT e kentse fiber ea khalase, fiber ea khalase le matla a bonding a PBT a molemo, ka PBT resin e kentse palo e itseng ea fiber ea khalase, eseng feela e ka bolokang PBT resin lik'hemik'hale tse hanyetsang, ts'ebetso le melemo e meng ea pele, empa hape e ka ba le keketseho e batlang e le kholo ea thepa ea eona ea mochini, le ho hlola maikutlo a PBT resin notch.
2. Phetoho e thibelang malakabe
PBT ke polyester e nkhang hamonate e nkhang hamonate, e se nang lelakabe le lelakabe, lelakabe la eona le sa sebetseng ke UL94HB, feela ka mor'a ho eketsoa ha lelakabe la lelakabe, le ka fihla UL94V0.
Li-flame retardants tse sebelisoang hangata li na le bromide, Sb2O3, phosphide le chloride halogen flame retardants, joalo ka tse ling tse leshome tsa bromine biphenyl ether, e bile eona PBT e kholo, e thibelang lelakabe, empa ka lebaka la ts'ireletso ea tikoloho, linaha tsa Europe li thibetse nako e telele ts'ebeliso. mekha e batla e ncha, empa ha e na molemo oa ts'ebetso e bile li-substitutes tse fetang leshome tsa bromine biphenyl ether.
3. Phetoho ea motsoako oa motsoako
Morero o ka sehloohong oa ho kopanya PBT le li-polymers tse ling ke ho ntlafatsa matla a ts'usumetso, ho ntlafatsa deformation ea warping e bakoang ke shrinkage ea mold, le ho ntlafatsa ho hanyetsa mocheso.
Ho kopanya ho sebelisoa haholo ho e fetola lapeng le kantle ho naha. Li-polymers tse ka sehloohong tse fetotsoeng tse sebelisetsoang ho kopanya PBT ke PC, PET, joalo-joalo. Mofuta ona oa lihlahisoa o sebelisoa haholo-holo likoloing, lisebelisoa tsa elektronike le lisebelisoa tsa motlakase. Karolo ea fiber ea khalase e fapane, 'me tšimo ea eona ea kopo le eona e fapane.
Lisebelisoa tsa mantlha tsa lisebelisoa tsa PBT
1. Lisebelisoa tsa elektronike
Ha ho na fuse breaker, electromagnetic switch, drive back transformer, handle appliance home, connector, joalo-joalo PBT e atisa ho eketsoa 30% khalase ea fiber e kopanyang e le sehokelo, PBT e sebelisoa haholo ka lebaka la thepa ea mechine, ho hanyetsa solvent, ho etsa ts'ebetso le theko e tlaase.
2. Fen ea ho senya mocheso
Glass fiber e matlafalitsoeng ka PBT e sebelisoa haholo ho fene ea mocheso oa mocheso, mocheso oa mocheso oa mocheso o behoa mochine ka nako e telele ho thusa ho senya mocheso, thepa ea 'mele ea litlhoko tsa polasetiki e na le ho hanyetsa mocheso, ho chesa, ho kenya letsoho le matla a mochine, PBT ke hangata ka sebopeho sa 30% faeba sebelisoa e le fene qhala mocheso ka ntle foreime le fene blade coil shaft.
3. Likarolo tsa motlakase
PBT e matlafalitsoeng ka khalase e boetse e sebelisoa e le transformer, relay ka hare ho shaft ea coil, ka kakaretso PBT hammoho le fiber 30% ea ho etsa ente. Lintho tse hlokahalang tsa 'mele tsa mochini oa li-coil li kenyelletsa ho kenya letsoho, ho hanyetsa mocheso, ho hanyetsa welding, fluidity le matla, joalo-joalo Thepa e loketseng ke GLASS fiber reinforced PBT, GLASS FIBER e matlafalitsoe PA6, GLASS FIBER e matlafalitsoeng PA66, joalo-joalo.
4. Aotomotivelikarolo
A. Likarolo tsa ka ntle: haholo-holo bumper ea koloi (PC / PBT), lemati la monyako, lattice ea sekhutlo, sekoahelo sa lesoba la mocheso oa enjene, khetla ea koloi ea koloi ea koloi, fender, sekoahelo sa terata, lebokose la lisebelisoa tsa koloi, joalo-joalo.
B. Likarolo tse ka hare: haholo-holo li kenyelletsa brace ea endoscope, bracket ea wiper le valve ea tsamaiso ea taolo;
C, likarolo tsa motlakase oa likoloi: li-coil twist tube tsa koloi le lihokelo tse fapaneng tsa motlakase, jj.
Ka nako e ts'oanang, e ka boela ea sebelisoa ho khetla ea lithunya tsa likoloi tse ncha tsa matla.
5. Lisebelisoa tsa mechine
Lisebelisoa tsa PBT li boetse li sebelisoa haholo ho video ea "tape recorder belt drive shaft", sekoaelo sa k'homphieutha, lebone la lebone la mercury, sekoahelo sa tšepe, likarolo tsa mochine oa ho baka le lisebelisoa tse ngata, CAM, konopo, ntlo ea ho shebella ea elektroniki, likarolo tsa khamera (ka mocheso, litlhoko tse thibelang mollo. )
