I-Hydroxypropyl Methyl Cellulose (HPMC) yokukhishwa kwamathayela

ethula:

IHydroxypropyl methylcellulose (HPMC) iyi-polymer eguquguqukayo esetshenziswa kabanzi embonini yezokwakha, enye yezinhlelo zayo ezivelele iwukugxusha amathayela. I-tile grout idlala indima ebalulekile ekuthuthukiseni ubuhle nokuqina kwezindawo zamathayili. Njengesengezo ekwakhiweni kwe-tile grout, i-HPMC inezinhlobonhlobo zezakhiwo ezizuzisayo, okuyenza ibe isithako esibalulekile emisebenzini yokwakha yesimanje.

1. Ukusebenza kwe-HPMC:

Isakhiwo samakhemikhali:

I-HPMC iyi-ether ye-cellulose eguquliwe etholakala ku-cellulose yemvelo.

Isakhiwo samakhemikhali siqukethe umgogodla we-cellulose lapho i-hydroxypropyl kanye namaqembu e-methyl enamathiselwe khona.

Ukugcinwa kwamanzi:

I-HPMC inezinto ezinhle kakhulu zokugcina amanzi, okubalulekile ku-tile grout ukuze kugcinwe ukusebenza futhi kuvimbele ukomiswa ngaphambi kwesikhathi.

Ikhono lokujiya:

Amandla okujiya e-HPMC asiza ukukhulisa ukufana kwe-grout, iqinisekise ukusetshenziswa kalula kanye nokunamathela okuthuthukisiwe endaweni yamathayili.

Setha ukulawula isikhathi:

I-HPMC isiza ukulawula isikhathi sokusetha se-tile grout, okuvumela ukulungiswa okufanele nokuqondanisa kwamathayela ngaphambi kokuba i-grout iqine.

Thuthukisa ukunamathela:

Izinto zokunamathisela ze-polymer zithuthukisa isibopho phakathi kwe-grout ne-tile, zikhulise ukuqina futhi zinciphise ubungozi bokuhluleka kwe-grout.

2. Iqhaza le-HPMC ku-ceramic tile grouting:

Ukugcinwa kwamanzi nokusebenza:

Amandla okubamba amanzi e-HPMC aqinisekisa ukuthi i-grout ihlala isetshenziswa isikhathi eside, okuvumela ukusetshenziswa kalula nokugcwaliswa kahle kwamalunga.

Ubukhulu nobukhulu:

Isenzo sokujiya se-HPMC sisiza ukufeza ukufana kwe-grout efiselekayo, ukuvimbela ukuwohloka nokuqinisekisa ukumbozwa kwezindawo eziqondile nezivundlile.

Setha ukulungisa isikhathi:

Ngokulawula isikhathi sokusetha, i-HPMC ingakwazi ukuzivumelanisa nezimo nezishintshayo kuzinga lokushisa kanye nomswakama.

Ukuqina okuthuthukisiwe:

Izakhiwo zokunamathela ezithuthukisiwe ze-HPMC zisiza ukuthuthukisa ukuqina kukonke kwe-tile grout, kunciphisa amathuba okuqhekeka nokuhlakazeka ngokuhamba kwesikhathi.

ezintathu. Inqubo yokukhiqiza ye-HPMC ye-tile grouting:

Ukukhetha impahla eluhlaza:

Ukukhiqizwa kwe-HPMC kuqala kukhetha i-cellulose yekhwalithi ephezulu njengempahla eluhlaza, ngokuvamile ephuma ku-pulp yokhuni noma ukotini.

Inqubo ye-Etherification:

I-Cellulose yenziwa i-etherified ngokwethula i-hydroxypropyl kanye namaqembu e-methyl ukuze akhe i-HPMC.

Ukuhlanzwa nokomiswa:

I-HPMC ehlanganisiwe iyahlanzwa ukuze isuse ukungcola bese yomiswa ukuze kutholwe impushana yokugcina noma ifomu eliyimbudumbudu elifanele ukufakwa ekwakhiweni kwe-tile grout.

I-QC:

Izinyathelo eziqinile zokulawula ikhwalithi ziyasetshenziswa ukuze kuqinisekiswe ukuthi i-HPMC ihlangabezana nezicaciso ezidingekayo ezifana ne-viscosity, usayizi wezinhlayiyana kanye nomswakama.

Ezine. Amanothi ohlelo lokusebenza:

Umthamo kanye nokwakhiwa:

Inani elifanele le-HPMC ekwenziweni kwegrout yethayela lincike ezintweni ezifana nokuvumelana okufunayo, isikhathi sokusetha kanye nezidingo ezithile zohlelo lokusebenza.

Inqubo yokuhlanganisa:

Izinqubo zokuxuba ezifanele zibalulekile ukuze kuzuzwe ukuhlakazwa okufanayo kwe-HPMC kungxube ye-grout, ukuqinisekisa ukusebenza okungaguquki, nokugwema ukunqwabelana.

isici semvelo:

Phakathi nezigaba zokufaka isicelo nezokuphulukisa, izici zemvelo ezifana nezinga lokushisa kanye nomswakama kufanele zicatshangelwe ukuze kuthuthukiswe ukusebenza kwe-HPMC ku-tile grout.

Ukuhambisana nezithasiselo:

Ukuhambisana nezinye izithasiselo, ezifana ne-pigment noma ama-antimicrobial, kufanele kuhlolwe ukuze kuqinisekiswe ukuthi ukusebenza okuphelele kwe-tile grout akuthikameki kabi.

5. Isiphetho:

IHydroxypropyl methylcellulose (HPMC) idlala indima ebalulekile ekuthuthukiseni ukusebenza kwama-tile grouts ezinhlotsheni zokwakhiwa kwezinhlelo zokusebenza. Izici zayo eziyingqayizivele, ezihlanganisa ukugcinwa kwamanzi, amandla okuqina nokusetha isikhathi sokulawula, kusiza ukuthuthukisa ukusebenza, ukunamathela kanye nokuqina kokwakhiwa kwe-tile grout. Ukuqonda izakhiwo namandla e-HPMC, kanye nokukhiqizwa okufanele nokucatshangelwa kwesicelo, kubalulekile ukuze uthole imiphumela engcono kakhulu kuphrojekthi yakho yokugxusha amathayili. Njengoba izinqubo zokwakha ziqhubeka nokuvela, i-HPMC isalokhu iyisengezo esibalulekile nesiguquguqukayo ekuphishekeleni izinga eliphezulu, izindawo ezihlala isikhathi eside zamathayela e-ceramic.
