HPMC-ithayile adhesive ifomula kunye nokusetyenziswa

I-adhesives ye-tile idlala indima ebalulekileyo kwishishini lokwakha, iqinisekisa ukudibanisa okukhuselekileyo kweetayile kwii-substrates ezahlukeneyo.IHydroxypropyl Methylcellulose (HPMC) sisithako esiphambili kwizinto ezininzi zokuncamathelisa iithayile zanamhlanje, ezibonelela ngeempawu zokuncamathelisa eziphuculweyo kunye nokusebenza.

1.Ukuqonda iHydroxypropyl Methylcellulose (HPMC):

I-HPMC iphuma kwiselulosi edla ngokusetyenziswa kwizinto zokwakha zokuncamathelisa, ukujiya, kunye neempawu zokugcina amanzi.

Ithathwe kwi-cellulose yendalo kwaye iqhutywe ibe ngumgubo ococekileyo.

I-HPMC iphucula amandla okubambisa iintambo zokuncamathelisa iithayile ngelixa ziphucula ukusebenza kwazo kunye neempawu zokugcina amanzi.

2.Ukwenziwa kwe-HPMC-Isekwe kwi-Tayile encamathelayo:

a.Izithako ezisisiseko:

Isamente yasePortland: Ibonelela nge-arhente ebophelelayo ephambili.

Isanti ecolekileyo okanye isigcwalisi: Iphucula ukusebenza kakuhle kwaye inciphise ukushwabana.

Amanzi: Ayimfuneko kumanzi kunye nokusebenza.

I-Hydroxypropyl Methylcellulose (HPMC): Isebenza njenge-ejenti yokuqina kunye ne-bonding.

Izongezo: Isenokubandakanya izilungisi zepolymer, izisasazi, kunye ne-anti-sag agents zokuphucula ukusebenza okuthe ngqo.

b.Ukulinganisa:

Umlinganiselo wesithako ngasinye uyahluka ngokuxhomekeke kwizinto ezifana nohlobo lwethayile, i-substrate, kunye neemeko zokusingqongileyo.

Ukuqulunqwa okuqhelekileyo kunokubandakanya i-20-30% yesamente, i-50-60% yesanti, i-0.5-2% ye-HPMC, kunye nomxholo wamanzi ofanelekileyo ukufezekisa ukufana okufunekayo.

c.Inkqubo yokuxuba:

Yomisa xuba isamente, isanti, kunye ne-HPMC ngokucokisekileyo ukuqinisekisa ukuhanjiswa okufanayo.

Yongeza kancinci amanzi ngelixa udibanisa de kube ukuhambelana okufunwayo kufezekiswe.

Xuba de kufumaneke intlama egudileyo, engenaziqhuma, uqinisekise ukugalelwa ngokufanelekileyo kwamasuntswana esamente kunye nokusasazwa kweHPMC.

3.Ukusetyenziswa kwe-HPMC-Isekwe kwiThayile yokuncamathelisa:

a.Ukulungiswa komphezulu:

Qinisekisa ukuba i-substrate icocekile, ilungile, kwaye ayinaluthuli, igrisi, kunye nezingcolisi.

Umphezulu orhabaxa okanye ongalinganiyo unokufuna ukunyuswa okanye ukubekwa kuqala phambi kokuba kufakwe incamathelisa.

b.IiNdlela zokuSebenza:

I-Trowel Application: Eyona ndlela ixhaphakileyo ibandakanya ukusebenzisa i-notched trowel ukusabalalisa i-adhesive kwi-substrate.

I-Back-buttering: Ukusebenzisa i-adhesive layer of adhesive back to the back of the tiles before set them in adhesive bed to improved bonding, ingakumbi kwiitiles ezinkulu okanye ezinzima.

I-Spot Bonding: Ifanele iithayile ezikhaphukhaphu okanye izicelo zokuhombisa, kubandakanya ukusebenzisa i-adhesive kumabala amancinci kunokuba isasaze kuyo yonke i-substrate.

c.Ukuhlohla iThayile:

Cinezela iileyile ngokuqinileyo kwibhedi yokunamathela, uqinisekise ukudibanisa ngokupheleleyo kunye nokugubungela okufanayo.

Sebenzisa izikhewu ukugcina amalungu egrout angaguqukiyo.

Lungisa ulungelelwaniso lwe-tile ngokukhawuleza phambi kokuba i-adhesive iseti.

d.Ukuhlamba kunye nokucoca:

Vumela i-adhesive ukuba iphilise ngokwemiyalelo yomenzi ngaphambi kokuba i-grouting.

Gcoba iileyili usebenzisa i-grout material efanelekileyo, ugcwalise amajoyina ngokupheleleyo kwaye ululaze umphezulu.

4.Izinto eziluncedo ze-HPMC-Isekwe kwi-Tile Adhesive:

Amandla oBonding ophuculweyo: I-HPMC iphucula ukubambelela kwiitile zombini kunye ne-substrates, ukunciphisa umngcipheko wokuchithwa kwe-tile.

Ukuphuculwa kokuSebenza okuPhuculweyo: Ubukho be-HPMC buphucula ukusebenza kunye nexesha elivulekileyo le-adhesive, evumela ukuba kube lula ukusetyenziswa kunye nokulungiswa kweetayile.

Ukugcinwa kwamanzi: I-HPMC inceda ukugcina ukufuma ngaphakathi kwe-adhesive, ukukhuthaza ukuhanjiswa okufanelekileyo kwesamente kunye nokuthintela ukomisa kwangaphambi kwexesha.

I-adhesive yethayile esekwe kwi-HPMC ibonelela ngesisombululo esithembekileyo kwizicelo ezahlukeneyo zokubeka iithayile, ukubonelela ngokuncamathela okuqinileyo, ukuphucuka kokusebenza, kunye nokuqina okwandisiweyo.Ngokuqonda ukuqulunqwa kunye nobuchule bokusebenzisa obuchazwe kwesi sikhokelo, iingcali zokwakha zinokusebenzisa ngokufanelekileyo ii-adhesives ze-HPMC ukuphumeza ukufakwa kweethayile ezikumgangatho ophezulu.
