Tekereza gukoresha PTFE yubushyuhe bwo hejuru mubikoresho bya chimique, gupfunyika umugozi wo mu nyanja, cyangwa gukoresha kashe yo mumazi. Kaseti yarengewe n'ibyumweru cyangwa ukwezi. Bizakomeza? Ibifatika bizananirana? Ese fiberglass izoroshya?
Igisubizo ntabwo cyoroshye. PTFE ubwayo - 'Umwami wa Plastiki ' - ni chimique yinjiza ibintu hafi ya byose. Ariko kaseti ya PTFE ntabwo irenze PTFE gusa: ifite substrate ya fiberglass hamwe na adhesifike yumutwe (PSA) inyuma. Ibi bice bitwara bitandukanye cyane mugihe cyo kwibizwa igihe kirekire.
Aokai PTFE yagerageje amanota menshi ya kaseti mubihe byo kwibiza. Iyi ngingo igabanya ingaruka ziterwa n’amazi, amazi yumunyu, nigisubizo cyimiti - ikanasobanura ubwoko bufatika bubaho.
Ihame rusange - PTFE Substrate irakomeye, ifata ni ntege
Kuri kaseti ya PTFE yubushyuhe bwo hejuru mugihe cyo kwibiza igihe kirekire, imikorere rusange irashobora kuvugwa muri make nka:
Ibikoresho fatizo bya PTFE: Byiza - muburyo bwa chimique inert, idakurura, ihagaze neza.
Fiberglass substrate: Vulnerable - irashobora koroshya mumazi mugihe kinini.
Igice gifatika: Ingingo nyamukuru idakomeye - igabanuka mugihe kinini cyo guhura namazi, imashanyarazi, cyangwa imiti.

Ingaruka z'igihe kirekire cyo kwibiza mu mazi
Uburyo amazi agira ingaruka kuri kaseti:
Igice gifatika: Umuvuduko ukabije wa silicone wifata ucika intege kubera kumara igihe kinini uhura na molekile zamazi. Amazi yinjira mumashanyarazi-substrate, agabanya gufatira hamwe amaherezo bikananirana burundu. Imbaraga zishishwa zirashobora kugabanuka kugera kuri 40% nyuma yamasaha 48 yo kwibiza mumazi.
Fiberglass substrate: Amaseti menshi yubucuruzi PTFE yubushyuhe bwo hejuru ikoresha imyenda ya fiberglass yatewe na PTFE nka substrate. Fiberglass izoroshya mumazi mugihe kinini, biganisha ku kugabanuka kwimbaraga rusange za kaseti. Iyi ni inzira itinda (ibyumweru ukwezi) ariko ntibisubirwaho.
Ni ryari kwibiza mu mazi byemewe?
Guhuza igihe gito (kwoza, kumenagura, gusukura muri make) - neza.
Kwibiza cyane muminsi cyangwa ibyumweru - ntibisabwa kuri kaseti isanzwe ya silicone PSA.
Kugirango ukoreshe amazi mumazi, tekereza kaseti idafite PTFE idafite imashini.
Aokai PTFE iragira inama abakiriya ko kaseti ya silicone isanzwe ya PSA ikwiranye nogukoresha amazi rimwe na rimwe (urugero, gutunganya ibiryo byoza ibiryo) ariko ntibikwiye kwibiza bikabije kurenza amasaha 72. Kumwanya muremure, turasaba fluorosilicone yomeka cyangwa amanota adafite.
Kwibiza mumazi yumunyu - Ibyago byinshi
Ugereranije n’amazi meza, amazi yumunyu atera ubwoba bwinshi:
Iyoni ya Chloride yihuta kwinjira no kwangirika kurwego.
Amazi yumunyu atera kwangirika gukabije kwa fibre yububiko - fibre yikirahure irashobora gutemba no gucika intege.
Korohereza umunyu mugihe cyumye birashobora guhungabanya uburyo bwo gufatana.
Icyifuzo: Ntugakoreshe kaseti isanzwe ya PTFE kugirango ushire mumazi maremare yumunyu (urugero, gupfunyika insinga zo mu nyanja, ibyuma bifata amazi). Koresha paruforopolyether (PFPE) ifata cyangwa idafite PTFE idafite imashini ifatanye.
Kwibiza Imiti - Biterwa rwose na Adhesive
Kaseti ya PTFE irusha imbaraga kurwanya imiti - ariko ibi ahanini biterwa nubwoko bufatika. Ingaruka ziterwa no kwibizwa mu miti ziratandukanye cyane.

Muncamake , PTFE yubushyuhe bwo hejuru irashobora gukoreshwa mugukoresha kwibiza - ariko mugihe gusa wunvise ingingo zintege nke. Substrate ya PTFE ni hafi gutsindwa. Fiberglass irashobora kwibasirwa. Ibifatika ningaruka zambere zo gutsindwa.
Kubiza amazi meza munsi yamasaha 72, silicone isanzwe PSA iremewe. Kumara igihe kirekire, amazi yumunyu, cyangwa imiti ikaze, uzamure kuri fluorosilicone, icyuma cya PFPE, cyangwa - ikiruta byose - kaseti ya PTFE idafite ibyuma bifata imashini.
Ukeneye kaseti ya PTFE kubidukikije byihariye? Aokai PTFE itanga amahitamo menshi kandi irashobora gutanga amakuru yikizamini kumiterere yawe. Twandikire hamwe nigihe giciriritse, ubushyuhe, nigihe giteganijwe kwibiza.
