Iipropati kunye neViscosity ye-CMC

I-Polyvinyl alcohol (PVA) yipolymer esetyenziswa ngokubanzi efumana izicelo njengeglue okanye i-adhesive kumashishini ahlukeneyo. Nazi ezinye iinyani eziphambili malunga nePolyvinyl Alcohol njengeglu:

1. Amanzi aNyibilikayo:

I-PVA i-soluble yamanzi, oku kuthetha ukuba inokunyibilika ngokulula emanzini ukwenza isisombululo se-viscous. Le propati yenza i-PVA glue ibe lula ukuyisebenzisa kwaye ivumela ukucocwa lula ngamanzi.

2. Ayinatyhefu kwaye ikhuselekile:

Iglu yePVA ngokuqhelekileyo ayinayo ityhefu kwaye ikhuselekile ukusetyenziswa kwizicelo ezahlukeneyo, kubandakanya ubugcisa kunye nobugcisa, ukwenza amaplanga, kunye neeprojekthi zephepha. Ihlala ikhethwa ukuba isetyenziswe ezikolweni, ezindlini, nakwiiprojekthi ze-DIY ngenxa yeprofayili yokhuseleko.

3. Ukuncamathelisa izinto ezininzi:

Iglu yePVA ibonisa ukuncamathela okugqwesileyo kuluhlu olubanzi lwee-substrates, kubandakanya iphepha, umthi, ilaphu, ikhadibhodi, kunye nezixhobo ezirhabaxa. Ngokuqhelekileyo isetyenziselwa ukudibanisa iphepha, ikhadibhodi, kunye neenkuni kwimisebenzi yezandla, ukwenza amaplanga, ukudibanisa iincwadi kunye nokupakisha izicelo.

4. Yomisa ngokucacileyo:

Iglu ye-PVA iyoma ukuya ekugqityweni okucacileyo okanye okuguquguqukayo, ingashiyi intsalela ebonakalayo okanye i-discoloration kwindawo edibeneyo. Oku kuyenza ilungele izicelo apho i-aesthetics ibalulekile, njengobugcisa bephepha, ikholaji, kunye neeprojekthi zokuhombisa.

5. Ibhondi eyomeleleyo:

Xa isetyenziswe ngokufanelekileyo kwaye ivunyelwe ukuba yome, i-PVA glue yenza ibhondi eyomeleleyo kunye neyomelele phakathi kwe-substrates. Inika i-tack yokuqala elungileyo kunye namandla okubambelela, kunye namandla abalaseleyo ebhondi ngokuhamba kwexesha.

6. Iinkcazelo ngeempawu eziguquguqukayo:

Iimpawu zeglue zePVA zinokutshintshwa ngokuhlengahlengisa izinto ezinje ngoxinaniso, i-viscosity, kunye nezongezo. Oku kuvumela ukwenziwa ngokwezifiso kweglue ukuba ihambelane neemfuno ezithile zesicelo, njengamandla ebhondi efunwayo, ixesha lokumisa, kunye nokuguquguquka.

7. Esekwe emanzini kunye ne-Eco-Friendly:

Iglu ye-PVA isekelwe kumanzi kwaye ayinayo i-volatile organic compounds (VOCs) okanye iikhemikhali ezinobungozi, okwenza ukuba ivumelane nokusingqongileyo. Iyabola kwaye inokulahlwa ngokukhuselekileyo kwiinkqubo ezininzi zenkunkuma zikamasipala.

8. Usetyenziso:

Iglu yePVA isetyenziswa kuluhlu olubanzi lwezicelo, kubandakanya:

• Ubugcisa kunye nemisebenzi yezandla: ikholaji, i-mache yephepha, i-scrapbooking
• Ukusebenza ngamaplanga: i-joinery, i-veneering, i-laminating
• Ukudibanisa iincwadi: amaphepha abopha incwadi kunye namaqweqwe
• Ukupakishwa: ukutywina iibhokisi zekhadibhodi, iibhokisi, kunye nemvulophu
• Umqhaphu: Ilaphu elidityanisiweyo elenziwe ekuthungeni nasekuveliseni impahla

9. Ukwahluka kunye noKuqulunqwa:

Iglu ye-PVA ifumaneka ngeendlela ezahlukeneyo, kubandakanywa ulwelo, ijeli, kunye neefom eziqinileyo. Isenokuguqulwa kunye nezongezelelo ezifana neplastiki, i-thickeners, kunye ne-agent edibanisa ukuwela ukunyusa iipropati ezithile okanye iimpawu zokusebenza.

Isiphelo:

Iglu yePolyvinyl Alcohol (PVA) incamathelisa ngeendlela ezininzi ezinoluhlu olubanzi lwezicelo kubugcisa kunye nemisebenzi yezandla, ukwenza amaplanga, ukupakisha, iingubo, kunye namanye amashishini. Ubume bayo bokunyibilika kwamanzi, ubutyhefu, ukuguquguquka, kunye neepropathi ezinamandla zokudibanisa zenza kube lukhetho oludumileyo lokudibanisa ii-substrates ezahlukeneyo kwizicelo ezahlukeneyo. Ingaba isetyenziswe ezikolweni, kwimizi, okanye kwi-industrial setting, i-PVA glue inikeza isisombululo esinokwethenjelwa nesisebenzayo sokubambisana kunye neemfuno zendibano.
