Nta: tus nqi qis, qes qes, pob tshab, ruaj khov loj, hluav taws xob tsis kam (tiv thaiv kab mob)
5.Polypropylene (PP)
KEV SIV: cov khoom siv pov tseg, cov txuas, pob tshab npog yas, quav nyab, niam txiv txhaj tshuaj pob khoom noj khoom haus, lim zaj duab xis.
Cov yam ntxwv: non-toxic, tasteless, zoo txhua yam khoom, tshuaj lom neeg ruaj khov thiab kub ua hauj. Kev rwb thaiv tsev zoo, tsis muaj dej nqus, zoo hnyav tiv thaiv, roj tsis kam, tsis muaj zog acid tsis kam, tsis muaj zog alkali tsis kam, zoo molding, tsis muaj kev nyuaj siab ib puag ncig tawg. Tab sis moulding shrinkage tus nqi, kev tsim cov khoom tuab yooj yim rau cuab. Nto inert, nyuaj rau luam tawm thiab nplaum. Muaj peev xwm tuaj yeem plhuav, txhaj tshuaj molding, vuam, ua npuas dej, kub kub molding, ua haujlwm machining.
6. Thermoplastic polyurethane (TPU)
KEV SIV: kev kho mob lub raj yas, lub ntsej muag pa oxygen, lub siab lub plawv, cov khoom tso tshuaj, IV txuas, hnab roj hmab ntawm sphygometer, daim ntaub npog rau xa tshuaj.
Nta: zoo pob tshab, siab zog thiab tsim kua muag, tshuaj lom neeg hnav thiab hnav tsis kam; Lub hardness ntau yog dav, qhov saum npoo yog du, tshuaj tua kab mob thiab microorganism, muaj dej tsis kam tiv taus.
7. Cov Khoom Siv Polytetrafluoroethylene (PTFE)
SIV: rau tib neeg lub cev cov leeg ntshav, hlab ntsha, lub siab ntsws txoj hlab ntsws, lub ntsej muag tsom, lub pob qij txha, lub raj mis, lwm lub raj, lub raj mis, ntaub qhwv thiab lwm yam khoom siv kho mob. Nta: siab crystallinity, me me kev sib txhuam coefficient, zoo kub tiv thaiv, zoo tshuaj lom neeg ruaj khov, muaj zog acid thiab muaj zog puag thiab txhua yam ntawm cov kuab tshuaj organic tsis ua haujlwm nrog nws. Muaj cov roj ntsha zoo, muaj kev sib txuam ntawm cov ntshav, tsis muaj kev puas tsuaj rau tib neeg lub cev, tsis muaj qhov tsis zoo hauv lub cev uas tau cog, huab cua sov siab, tsim nyog siv rau hauv kev kho mob teb.
8. Cov Polyamide (PA)
Lub Hom Phiaj: hose, txuas, adapter, piston.
Nta: yooj, khoov tsis kam, siab toughness thiab tsis yooj yim tawg, tshuaj lom neeg kuj thiab hnav kuj. Tsis tso tawm cov tshuaj phem rau tib neeg lub cev, yog li ntawd tsis ua rau mob ntawm daim tawv lossis nqaij.
9. Polyether ether ketone (PEEK)
Daim ntawv thov: nws tuaj yeem hloov hlau rau cov khoom siv phais thiab kho hniav, hloov titanium alloy los ua cov pob txha mos. Thaum lub sijhawm kev kuaj mob tsawg kawg ntawm kev phais mob me me, cov twj siv hlau yuav ua rau cov duab cuav lossis cuam tshuam rau tus kws kho mob hauv thaj chaw phais. PEEK yog tawv li cov hlau tsis huv, tab sis nws tsis tsim cov khoom cuav.
