1. POM
POM feem ntau hu ua Saigang. Qhov laj thawj vim li cas nws thiaj li hu ua Saigang feem ntau yog vim nws qhov nyuaj siab, nrog Rockwell hardness ntawm D80-85Z. POM yog cov khoom siv feem ntau siv hauv cov tshuab tsis siv neeg. Qhov saum npoo ntawm cov khoom no yog lubricated thiab hnav-resistant. Nws tuaj yeem siv tsis tu ncua ntawm qhov kub ntawm -40 degree txog 100 degree . Siv rau qhov sib sib zog nqus qhov chaw xws li shafts lossis gears.
Cov lus Askiv luv luv (PTFE) tseem hu ua huab tais ntawm cov yas, Teflon, Teflon yog cov khoom siv polymer. Nws tiv taus qhov kub thiab txias, thiab tuaj yeem ncav cuag {{0}} degree rau 260 degree . Kev sib txhuam coefficient tsawg heev, thiab kev sib txhuam nrog cov ntaub ntawv hlau tuaj yeem ncav cuag 0.04, uas yog ze rau kev sib txhuam. Nws kuj yog ib qho ntawm cov khoom siv corrosion-resistant tshaj plaws nyob hauv lub ntiaj teb. Nws tuaj yeem tiv taus cov kuab tshuaj organic.
Cov khoom siv kuj yog mos, nyuaj rau kev ua, yooj yim rau deform, thiab tsis tuaj yeem ua cov khoom siv siab. Feem ntau siv rau hauv kev tsim khoom siv rau qhov hnav-tiv taus, xws li cov lus qhia, w-shaped seals, thiab lwm yam.
Nylon yog ib qho ntawm cov khoom siv feem ntau siv hauv cov tshuab tsis siv neeg. Cov khoom siv yog hnav-resistant thiab nws tus kheej-lubricating, thiab tuaj yeem lubricated ntawm qhov kub thiab txias kom nws cov kev sib txhuam coefficient tsawg heev. Cov khoom muaj qhov tseeb geometric siab thiab tuaj yeem ua cov iav bearings thiab lwm yam. Lub siab kub kuj tuaj yeem ncav cuag 160 degree, thiab nws tuaj yeem siv tsis tu ncua, tab sis nws yooj yim nqus dej thiab nthuav dav thaum ntub dej, uas yuav cuam tshuam rau qhov raug.
Lub npe polyethylene, cov khoom siv yog pheej yig thiab dav siv, thiab nws kuj yog ib qho ntawm cov khoom siv feem ntau siv rau cov tshuab tsis siv neeg. PVC muaj cov khoom siv los tiv thaiv zoo li qub thiab tsis muaj qhov zoo li qub. Hauv cov khoom siv hluav taws xob, txoj siv sia siv yog anti-static. Kuj tseem muaj qhov sib txawv ntawm cov khoom siv tawv PVC thiab cov khoom muag muag. Feem ntau, cov khoom uas bears lub load yog cov ntaub ntawv nyuaj, xws li tooling boards. Lub melting point ntawm cov khoom no yog 75-90 degree . Cov khoom no tsis tuaj yeem siv thaum nws nyob rau hauv kev sib cuag nrog cov zaub mov, vim tias qhov kub thiab txias yuav tso cov carcinogens.
Nws yog hu ua PU, tseem hu ua PU, uas muaj cov roj zoo, tawv tawv, hnav tsis kam, kev laus ua haujlwm thiab adhesion; nws muaj lub rigidity ntawm yas thiab elasticity ntawm roj hmab. Kev lag luam tshwj xeeb (PU); log, duav log, skateboard log, pa luam yeeb tshuab log, bearing log, tsav tsheb, thiab lwm yam .; suab-absorbing txheej, seals, buffer hau, buffers, anti-scratch qhov chaw, anti-scratch qhov chaw, fixture pads, Lub teeb yuag cushion feem ntau siv polyurethane.
ABS yas yog ib qho resin ua los ntawm peb lub monomers, A (acrylonitrile) B (butadiene) S (styrene) thiab lawv cov ntsiab lus sib txawv tuaj yeem ua rau ntau yam resins. Ntawm cov tshuab, nws tsim nyog rau cov khoom siv dav dav, hnav-txo thiab hnav-tiv taus qhov chaw, thiab kis tau tus mob. ABS tseem yog ib qho ntawm cov ntaub ntawv tseem ceeb rau 3D luam ntawv, thiab nws kuj yog cov khoom ruaj khov tshaj plaws hauv 3D luam ntawv.
Xa mus rau cov khoom siv polymer uas muaj zog heev nrog thim rov qab deformation. Cov roj hmab uas ua rau kom muaj kev sib txhuam coefficient ntawm qhov chaw ntawm cov menyuam hauv lub tshuab yog cov roj hmab lagging, uas muaj kev hnav tsis kam thiab kev sib khi zoo. Cov roj foob thiab O-ring tag nrho yog ua los ntawm roj hmab. Tab sis cov roj hmab yuav muaj hnub nyoog, feem ntau tawg thiab tawv.
Lub npe tshuaj yog phenolic yas, uas muaj zog txhua yam thiab zoo hnav tsis kam. Muaj cov kev xaiv los tiv thaiv zoo li qub thiab tsis muaj kev tiv thaiv zoo li qub hauv kev xaiv. Nws tuaj yeem siv rau cov cuab yeej boards, fixture backing plates, thiab cov ntaub ntawv sib zog, tab sis nws cov khoom siv hluav taws xob kuj tsawg. Tsis zoo, qhov precision tom qab ua tiav tsis siab. Yog li ntawd, nws tsis tuaj yeem siv rau hauv cov tshuab uas lub load loj thiab qhov precision siab.
