Hauv cov ntawv thov kev lag luam, hoses yog cov khoom tseem ceeb uas yog siv los thauj cov ntaub ntawv ua kua, gases lossis lwm cov kua dej los ntawm ib qho mus rau lwm qhov. Hom hose siv yuav nyob ntawm cov kua uas tau thauj, lub siab xav tau thiab ib puag ncig. Hauv tsab xov xwm no, peb yuav sib piv thiab sib piv ob hom hoses: PTFE hoses thiab cov roj hmab zoo tib yam.
PTFE hoses yog tsim los ntawm PTFE (Polytetrafluoroethylene) cov khoom, uas yog ib hom thermoplastic polymer. Cov khoom no muaj cov khoom tshwj xeeb uas ua rau nws zoo meej rau kev siv hauv kev lag luam. PTFE hoses muaj kev ua haujlwm siab rau cov tshuaj thiab cov kuab tshuaj, qhov kub thiab txias thiab kev sib txhuam tsawg. Cov hoses no kuj yog qhov hnyav heev, uas ua rau lawv yooj yim los tuav piv rau lwm cov hoses hnyav.
Ntawm qhov tod tes, cov roj hmab zoo tib yam yog tsim los ntawm cov roj hmab ntuj lossis hluavtaws, uas yog cov khoom hnyav dua li PTFE. Cov roj hmab hoses feem ntau hloov tau ntau dua li PTFE hoses, tab sis lawv tsis tuaj yeem tswj qhov kub thiab txias xws li PTFE.
Cov hauv qab no yog qhov zoo thiab qhov tsis zoo ntawm PTFE hoses thaum piv rau cov roj hmab zoo tib yam.
Qhov zoo ntawm PTFE Hoses:
1. Tshuaj lom neeg thiab hnyav Resistance: PTFE hoses muaj tshuaj lom neeg ua haujlwm siab thiab tiv taus cov kuab tshuaj feem ntau. Qhov no ua rau lawv zoo tagnrho rau kev siv tshuaj, tshuaj, thiab zaub mov kev lag luam.
2. High-Temperature Resistance: PTFE hoses tuaj yeem tiv taus qhov kub thiab txias li ntawm -60 degree mus rau 260 degree, ua rau lawv haum rau siv nyob rau hauv high-temperature ib puag ncig.
3. Low-Friction: PTFE muaj ib coefficient ntawm kev sib txhuam tsis tshua muaj, ua rau nws haum rau siv nyob rau hauv cov ntaub ntawv uas cov kua yuav tsum tau ntws smoothly tsis muaj kev cuam tshuam.
4. Lub teeb yuag: PTFE hoses yog qhov hnyav heev, uas ua rau lawv yooj yim los tuav thiab txav mus rau hauv qhov chaw nruj.
Qhov tsis zoo ntawm PTFE Hoses:
1. Tus nqi siab: PTFE hoses yog kim dua li cov roj hmab hoses zoo tib yam.
2. Kev nruj: PTFE hoses tsis hloov pauv raws li cov roj hmab zoo tib yam, ua rau lawv nyuaj rau khoov lossis twist.
3. Tsis haum rau kev siv lub tshuab nqus tsev: PTFE hoses tsis haum rau kev siv lub tshuab nqus tsev vim lawv tsis tuaj yeem tiv taus qhov siab.
Qhov zoo ntawm Ordinary Rubber Hoses:
1. Flexibility: Cov roj hmab hoses hloov tau yooj yim dua li PTFE hoses, ua kom yooj yim rau khoov thiab twist nyob ib ncig ntawm qhov chaw nruj.
2. Nqi-zoo: Cov roj hmab hoses yog pheej yig dua li PTFE hoses.
3. Yooj yim rau nruab: Roj hmab hoses yog ib qho yooj yim rau nruab thiab tsis tas yuav muaj cov khoom tshwj xeeb.
Disadvantages ntawm Ordinary Rubber Hoses:
1. Chemical Resistance: Roj Hmab hoses tsis muaj cov tshuaj tiv thaiv tib yam li PTFE hoses.
2. Cov kev txwv kub: Cov roj hmab hoses tsis tuaj yeem tswj qhov kub ntawm qhov kub thiab txias PTFE hoses.
3. Nyhav: Cov roj hmab hoses hnyav dua li PTFE hoses, uas tuaj yeem ua rau lawv nyuaj thiab txav mus los.
Xaus:
Zuag qhia tag nrho, PTFE hoses yog qhov kev xaiv zoo tshaj plaws rau kev lag luam uas yuav tsum muaj tshuaj lom neeg ua haujlwm siab, qhov kub thiab txias, thiab kev sib txhuam qis. Txawm li cas los xij, yog tias tus nqi thiab kev hloov pauv tseem ceeb dua li tshuaj lom neeg lossis qhov kub thiab txias, ces cov roj hmab zoo tib yam yuav yog qhov kev xaiv zoo dua. Thaum kawg, kev xaiv ntawm PTFE thiab cov roj hmab zoo tib yam yuav nyob ntawm seb cov ntawv thov tshwj xeeb thiab ib puag ncig.
