◆Da farko, bari mu bincika na kowa ingancin matsaloli na redispersible latex foda, kazalika da na kowa hanyoyin da illolin unscrupulous masana'antun don rage farashin:

◆ Yadda za a bambanta ko gane ingancin redispersible latex foda? Don nemo hanya, fara da bincike:

1. Binciken alamun samarwa

Alamomi sune tushen don auna ingancin foda na latex mai sakewa. Ma'auni na ma'auni shine nau'in ƙididdiga na ainihin aikin aikin foda na polymer mai sakewa. Idan index kewayon redispersible polymer foda ya wuce ko kasa cika da misali, zai yi wani kai tsaye tasiri a kan yi. Babban dalilan da ke haifar da alamun rashin daidaituwa sune matsalolin samarwa, irin su fasahar samar da baya, kayan aiki na zamani ko tsufa, amfani da arha da ƙarancin albarkatun ƙasa, da duban masana'anta na samfuran da aka gama. Menene ƙari, wasu masana'antun suna da dama don rage farashi, ba tare da la'akari da inganci ba, da rashin ƙarfi. Sabili da haka, ya zama dole don zaɓar ƙwararrun masana'anta kuma abin dogaro na yau da kullun.

2. Binciken aikin asali

1. Redispersibility: latex foda tare da mai kyau redispersibility za a iya narkar da a cikin ruwa don samar da wani barga emulsion, da barbashi size rarraba ne kama da cewa na asali emulsion. Roba foda tare da rashin sakewa mara kyau, wanda ba za a iya daidaita shi daidai ba, kuma yana iya ƙunsar polymers marasa rarrabuwa.

2. Abubuwan da ke samar da fina-finai na foda na roba: kayan aikin fim sune tushen kayan gyaran turmi kamar mannewa. Maƙasudin ƙirƙirar fina-finai gabaɗaya ana haifar da su ta hanyar ƙari da yawa na abubuwan da ba su dace ba ko abubuwan da ba su dace ba. Kyakkyawan rarrabuwar latex foda mai kyau yana da kyawawan kaddarorin samar da fina-finai a cikin zafin jiki, kuma waɗanda ke da ƙayyadaddun kayan aikin fim a cikin zafin jiki galibi suna da matsalolin inganci dangane da polymer ko abun cikin toka.

3. Ruwan juriya na fim: Redispersible latex foda yana da kyawawan kayan aikin fim kuma yana da kyakkyawan juriya na ruwa. Foda na Latex tare da ƙarancin juriya na ruwa gabaɗaya sun ƙunshi ƙarin polymers masu narkewar ruwa.

3. Binciken tasirin aikace-aikacen

Ƙaddara bisa ga ƙa'idar aiki:

1. Ƙarfin haɗin bushewa da ƙarfin haɗin ruwa: haɗin ba shi da kyau, kuma akwai matsalolin inganci dangane da polymer ko ash.

2. Sauye-sauye da juriya mai tasiri: Ƙarfafawa ba shi da kyau, akwai matsalolin inganci a cikin polymer, kuma sassauci yana raguwa yayin amfani, wanda zai iya ƙunsar filastik.

3. Hydrophobic da wadanda ba hydrophobic: The surface ne sosai hydrophobic, wanda zai iya rage workability da bonding ƙarfi na turmi.

4. Flow da rheology: rheology ba shi da kyau, kuma akwai matsalolin inganci a cikin polymers ko additives.

5. Kumfa da defoaming: Halin kumfa mara kyau, matsalolin inganci tare da polymers, ash ko additives.

◆ Hanyoyi masu sauƙi da yawa don gano foda na latex mai sakewa:

1. Hanyar bayyanar: rufe karamin adadin redispersible latex foda thinly kuma a ko'ina a kan saman gilashin farantin karfe mai tsabta tare da gilashin sanda, sanya gilashin farantin a kan farar takarda, da kuma gani na duban bayyanar barbashi, kasashen waje abubuwa da coagulation .

2. Hanyar wargajewa: Ɗauki ɗan ɗanɗano kaɗan na garin latex wanda za'a iya sakewa sannan a saka shi cikin ruwa sau 5, fara motsawa sannan a jira minti 5 don gani. A ka'ida, ƙananan ƙwayar da ba a iya narkewa wanda ke haɗo zuwa ƙasan ƙasa, mafi kyawun ingancin foda mai lalacewa.

3. Hanyar toka: Sai ki dauko dan kadan daga cikin foda da za a iya sakewa, sai a auna shi, sai a zuba a cikin kwandon karfe, sai a yi zafi da shi zuwa kusan digiri 600, sai a kona shi da zafi mai tsanani kamar minti 30, sai a sanyaya shi zuwa daki, sannan a auna shi. sake. Kyakkyawan inganci don nauyin nauyi.

4. Yadda ake yin fim: Ɗauki ɗan ɗanɗano mai ɗanɗano mai ɗanɗano mai ɗanɗano, a zuba a cikin ruwa sau 2, a jujjuya shi daidai, a bar shi ya tsaya kamar minti 2, sake motsawa, da farko a zuba maganin a kan lebur gilashi, sai gilashin. shi a cikin inuwa mai iska. Bayan bushewa, lura cewa ingancin tare da babban nuna gaskiya yana da kyau.
