Yadda Ake Gwaji Ingancin Emulsion PTFE: Mahimman Mahimmanci 6 & Hanyoyi

PTFE emulsion - kuma aka sani da PTFE watsawa - shi ne albarkatun kasa don shafi fiberglass masana'anta don samar da PTFE masana'anta mai zafin jiki , kaset, da bel. Idan ingancin emulsion ɗin ya kashe, samfurin ƙarshe zai sami ƙarancin aikin da ba ya aiki, rashin daidaituwa, ko gazawar da bai kai ba.

Amma ta yaya za ku san idan tsari na PTFE emulsion yana da kyau? Ka gwada shi.

Aokai PTFE ya yi amfani da gwada PTFE emulsions na shekaru. Wannan jagorar ya ƙunshi manyan alamomin gwaji guda shida - m abun ciki, pH, girman barbashi, danko, kwanciyar hankali, da bayyanar - tare da daidaitattun hanyoyin da ma'aunin karɓa.

M abun ciki kai tsaye yana shafar aikin samfur da tattalin arzikin aikace-aikacen (mafi girman sutura yana buƙatar daskararru mafi girma).

Hanyoyin gwaji gama gari:

Sharuɗɗan karɓa:

• A cikin daidaitattun T/FSI 067-2021: Babban buƙatun abun ciki don mai da hankali na PTFE akai-akai shine 60± 2%

• Matsakaicin kulawa na kan-site na ainihi: 60 ± 0.5% (ƙaƙƙarfan haƙuri don daidaiton shafi)

Ƙimar pH - Ma'anar Ƙarfafawa

Ƙimar pH tana rinjayar kwanciyar hankali, lalata, da dacewa da sauran kayan.

Hanyar gwaji: Hanyar Gilashin Electrode (Ƙaddamar Kai tsaye) - auna ta amfani da pH mita tare da gilashin lantarki wanda aka daidaita ta hanyar daidaitawa mai maki biyu ko uku. Wannan ita ce daidaitacciyar hanyar da aka fi amfani da ita.

Sharuɗɗan karɓa:

• Ta T/FSI 067-2021: pH kewayon 9.0 - 11.0

• Sauye-sauye a cikin pH sau da yawa yana nuna rashin zaman lafiyar tsarin ko halayen sinadaran sun faru (misali, hydrolysis na surfactant)

• Bin diddigin canje-canjen pH na dogon lokaci yana da mahimmanci don yin la'akari da kwanciyar hankalin sinadarai na emulsion

Me yasa pH ke da mahimmanci: PTFE emulsions an daidaita su ta hanyar surfactants masu tasowa, waɗanda ke buƙatar yanayin alkaline (pH> 8) don kasancewa masu tasiri. Idan pH ya faɗi ƙasa da 8, emulsion na iya yin coagulate.

Aokai PTFE yana ba da shawarar gwada pH akan kowane drum mai shigowa da kowane wata yayin ajiya. Kwatsam kwatsam daga 10.2 zuwa 8.5 sama da makonni biyu yana nuna emulsion yana lalatawa kuma yakamata a yi amfani da shi nan da nan ko kuma a ƙi.

Girman Barbashi & Rarraba Girman Barbashi

Girman da rarraba daidaitattun abubuwan PTFE na farko suna da tasiri mai mahimmanci akan kaddarorin samar da fina-finai, haɓakawa, da aikin samfurin ƙarshe.

Hanyoyin gwaji:

Mabuɗin ƙima:

• D50 (diamita na tsakiya) - kewayon al'ada don emulsion PTFE: 0.1-0.3 microns

• Barbashi size rarraba nisa - kunkuntar ne mafi alhẽri ga m shafi

• D10 da D90 - suna kwatanta yaduwar rarrabawa

Jagoran karɓa: Don yawancin aikace-aikacen shafi, D50 ya kamata ya kasance tsakanin 0.15 da 0.25 μm tare da 90% na barbashi a cikin ± 0.1 μm na ma'ana.

Dangantakarwa – Yin Aiwatar da Aiwatarwa

Danko characterizes kwarara hali, kai tsaye shafi shafi da impregnation matakai.

Hanyoyin auna gama gari:

Sharuɗɗan karɓa:

• Ta T/FSI 067-2021: Kewayon Danko 12.0 – 30.0mPa·s (a 25±1°C)

• Danko wanda yayi ƙasa da ƙasa → rashin daidaituwa, drips

• Danko wanda ya yi yawa → ƙarancin shiga cikin fiberglass, yana buƙatar dilution

Bayanin Aiki: Don tsoma rufin masana'anta na fiberglass, dankowar manufa shine yawanci 15-20mPa·s. Idan danko ya zube, daidaita tare da ruwa mai narkewa (zuwa ƙasa) ko ƙara mai kauri (don ɗagawa).

Ƙimar Ƙarfafawa - Ma'ajiya & Dogaran Sufuri

Ƙimar kwanciyar hankali yana tabbatar da emulsion ya kasance daidai lokacin ajiya da sufuri. Ana amfani da ingantattun hanyoyin gwaji don kwaikwayi yanayin dogon lokaci.

Sharuɗɗan wucewa/ gazawa:

• Babu bayyane delamination, sedimentation, ko gel samuwar

• Canjin danko <10% daga farko

• Girman barbashi D50 ya canza <15%

Jagoran rayuwar Shelf: Ƙarƙashin ma'auni mai kyau (10-30 ° C, hatimi), PTFE emulsion yawanci yana kula da kwanciyar hankali na watanni 6-12. Idan centrifuged gwajin ya nuna> 5% laka, jefar da tsari.

Duban Bayyanar - Duban daidaiton tsari mai sauri

Duba samfurin a gani a ƙarƙashin hasken halitta.

Siffar da aka yarda da ita: Fari ko haske rawaya emulsion, uniform, ba tare da lahani kamar delamination, kullun gel, samuwar fata, ko hazo bayyananne.

Abin da za a duba:

• Duhu → yuwuwar gurɓatawa ko lalata yanayin zafi

• Fatar a saman → bushewa ko ɓarna coagulation

• Lumps ko grit → polymer coagulated (mara kyau)

• Ruwa mai tsabta a saman → lalata ya faru
