Tafasa ko dawo da samfuran, waɗanda ke buƙatar babban aiki da tsananin juriya mai zafi, yakamata su dace da yanayin warkarwa wanda masana'anta mai haɗawa ke samarwa.

Lokacin warkarwa yakamata ya dace da ƙimar kammalawar amsawa, coefficient coefficient da aikin sealing zafi.

Samfurori na musamman na iya buƙatar zafin zazzabi mafi girma.

2.2 M Maɗaukaki mara ƙarfi

Idan aikin rufewa ya cika abin da ake buƙata, don samfuran laminating marasa ƙarfi, waɗanda fina -finai na ciki suna da ƙarancin yawa, adhesives suna da monomers masu yawa masu kyauta, yana da wahala a rufe su. Sabili da haka, ana ba da shawarar warkar da ƙarancin zafin jiki, don 38-40.

Idan ƙimar kammalawar ta cika abin da ake buƙata, ya kamata a yi la’akari da tsawon lokacin warkarwa.

Idan fina-finai na rufe zafi suna da yawa, zazzabin warkewa ya kamata ya zama 40-45. Idan ƙimar kammala martani da aikin rufe zafi yana buƙatar haɓaka, lokacin warkarwa ya kamata ya fi tsayi.

Tsanani gwaji dole ne kafin samar da taro, don tabbatar da inganci.

Menene ƙari, yakamata a yi la’akari da zafi. Musamman a busasshen hunturu, danshi mai dacewa na iya hanzarta haɓaka halayen.

2.3 Rufewar Ruwa

Lokacin laminating VMCPP, injin lamination dole ne ya bushe sosai, ko kuma aluminized Layer za a oxidized. A lokacin warkarwa, yawan zafin jiki kada ya yi yawa ko yayi ƙasa. Babban zafin jiki zai haifar da babban coefficient.

2.4 Mai narkewa mai narkewa

Yawanci zaɓi magani na halitta, amma aikin adhesion bayan narkewa ya kamata a lura.

3. Tsananta Kula da Zazzabi

Dangane da bincike, akan yanayin ƙimar amsawa, kusan babu wani martani a ƙarƙashin 30. Fiye da 30, kowane 10mafi girma, ƙimar amsa yana haɓaka kusan sau 4. Amma shiBa daidai ba ne don haɓaka zafin jiki don hanzarta saurin amsawa cikin makanta, yakamata a lura da abubuwa da yawaainihin ƙimar ƙima, ƙima coefficient da ƙarfin sealing zafi.

Don cimma sakamako mafi kyau na warkarwa, yakamata a raba zafin zazzabi zuwa fannoni daban -daban, gwargwadon finafinan lamination da sifofi.

A halin yanzu, matsalolin gama gari sune kamar haka:

Oneaya, zazzabin warkarwa yayi ƙasa kaɗan, yana yin ƙarancin ƙima, kuma samfurin yana da matsaloli bayan an rufe shi ko dafa shi.

Na biyu, zazzabin warkarwa ya yi yawa kuma fim ɗin sealing mai zafi yana da ƙarancin yawa. Samfurin yana da mummunan aikin sealing zafi, babban ƙwanƙwasawar gogayya da mummunan tasirin hanawa.
