Izibonelelo ze-HPMC ekwandiseni umlinganiso weemveliso ezisekwe

I-Hydroxypropyl Methylcelcelsulose (i-HPMC) yi-polymer eselwelwe ngamanzi asetyenziswa ngokubanzi kwizinto zokwakha, ngakumbi kwiimveliso ezisekwe kwisamente. Idlala indima ebalulekileyo kumanqanaba ohlukeneyo ngexesha lokwakha nasemva kokusetyenziswa, ngakumbi ekuphuculeni ubumbeleli.

1. Iimpawu ezisisiseko kunye nendlela yesenzo se-HPMC
Njengomntu ongenguye-i-ionlulose ether, i-HPMC inee-solinoity eziphezulu kunye nokuzinza kwe-viscofity. Isakhiwo sayo semolekyuli siqukethe amaqela e-hydroxyl kunye ne-AFGISY, ethi iyenza ukuba ihlengahlengise ngokufanelekileyo ukungqinelana, ukugcinwa kwamanzi kunye nokugcinwa kwamanzi kwi-chietimes paste. Xa i-HPMC ichithwe emanzini, isisombululo esenziwa sinezinto ezilungileyo ze-oyile, ukwenza ifilimu kunye neepropathi zevidiyo, ezisetyenziswa ngokubanzi kwizixhobo ezisekwe kwisamente.

Iziphumo zokuphucula umlinganiso ze-HPMC ikakhulu kwezi ndlela zilandelayo:

Ukugcinwa kwamanzi okuphuculweyo: I-HPMC inokunyusa umgangatho wokugcina amanzi kwi-Clumes, ngaloo ndlela uthintela amanzi ukuba alahleke ngokukhawuleza kwaye aqinisekise ukuba kwenziwe i-hydration eyaneleyo kwaye iqinisekisa umanzi ofanelekileyo wesamente. Impendulo ye-hydration yesamente yeyona nto iphambili ekumiseleni amandla kunye nokunamathela. Ukugcinwa kwamanzi i-HPMC kuphucula amandla okugqibela kunye nokubethelela izinto ezisekwe kwisamente.

Ukuphuculwa kokungaguquguquki kunye nokusebenza: i-HPMC inokunyusa kakhulu i-viscofity yezixhobo esekwe kwimo yesamente, ukuphucula ukungaguquguquki, yenza ukuba izinto zibe lula ukusebenza ngexesha lolwakhiwo, kwaye zinciphise ukungcungcutheka nokuwa. Ukongeza, i-HPMC inokuphucula iprinta yeplasitiki, isenza i-iyunifomu okanye ilele, kwaye iphucule ukusebenza ngokukuko.

Ukuphucula amandla e-bondile: I-HPMC inokuvelisa ubumbethe obuqinileyo kumphezulu we-substrate ngokwenza ifilimu emdaka ngokunamathela. Ingakumbi kwimitha enkulu okanye indawo egudileyo, i-HPMC inyusa amandla okunamathela phakathi kwezinto ezisekwe kwimo yesamente kunye nokuthintela ukuqhekeza okanye ukutshiswa kwezixhobo.

2. Izibonelelo ezithile ze-HPMC ekwandiseni umlinganiso weemveliso ezisekwe
Ukuphucula ukusebenza kunye nokugcinwa kodaka
Ukongeza i-HPMC kudaka kunokubangela ukungqinelana kwawo kunye nokubonakala kwe-viscofity, ukwenza ukwakhiwa kube lula, ngakumbi xa kusenziwa yingxaki ethembekileyo yodaka. Ingaphucula imbethensi phakathi kodaka kunye nomgangatho ophezulu, qinisekisa isicelo esifanayo, kwaye sinciphise inkunkuma kunye nenkunkuma ngexesha lokwakha.

Ukuphucula ukugcinwa kwamanzi kwaye kuncitshiswe ukuqhekeka
Ukugcinwa kwamanzi aphezulu e-HPMC kuphakama kakhulu kwiindawo ezomileyo. Inokuthintela ngokufanelekileyo ukuphuma kwamanzi ngokukhawuleza kwamanzi kwizixhobo ezisekwe kwimo yesamente emva kokwakha emva kokwakha kwaye kuqinisekiswe ukuba kwenziwe i-hdiment epheleleyo yesamente. Le ndlela yokugcina amanzi inciphisa ingxaki yokuqhekeka kwezinto ezibangelwa kukusoma okukhawulezayo, ngakumbi xa ukwakhiwa okukhulu kuyasebenza. Ngokwandisa inqanaba le-qumed hydration, amandla apheleleyo kunye nokuqina kwento leyo kuyaphuculwa.

I-Bonding ephuculweyo kunye nokuphuculwa komthendeleko kwindawo
Ipropathi yokwakha ifilimu ye-HPMC yenza ukuba kube senze ifilimu enamathelayo kumphezulu wezinto esekwe kwisamente, ukuphucula ukuboleka phakathi kweemveliso ezisekwe kwisamente kunye neentlobo zemihla ngemihla. Nokuba isetyenziselwa izixhobo ezifana nekhonkrithi, izitena okanye iibhodi ze-gypsim, i-HPMC inokubonelela ngokuthintela iingxaki ezinjengokuphalazwa, ukulibaziseka okanye ukungcungcutheka kwezinto zokuphuma. Oku kubaluleke kakhulu kwiimveliso ezinjenge-fer-fake fer kunye nee-tiles ezifunwayo ezifuna amandla aphezulu.

Ukuphuculwa kwentsebenzo yokuntywila okungathandekiyo
Ngexesha lokusetyenziswa kwezinto ezisekwe kwisamente, ngakumbi kumphezulu othe nkqo okanye kulwakhiwo lokwakha olunyukayo, kusoloko kudibana ukuba ii-SAGs zeZinto eziKwenzelwe amandla. I-HPMC inokuthintela ngempumelelo i-viscofity kunye nokungqinelana kweemveliso ezisekwe kwisamente, ukunqanda utshintsho kwiinguqu zabo ngenxa yokuhamba ngaphambi kokusongezwa, ngaloo ndlela kuphucule inani lokulungisa.

Ukuphucula ukuqina kunye nokunganyangeki
Umlinganiso onikezwe yi-HPMC akabonisi kuphela kwinkqubo yokwakha, kodwa nakwindlela yokuqina kunye nokuzinza emva kokusetyenziswa. Inokonyusa ukuguquguquka kunye nokunganyangeki kwezinto ezisekwe kwisamente, kwaye kuthintele ukuqhekeza kwizixhobo xa iqondo lobushushu litshintsha okanye amandla angalingani. Olu buqubli lwandisa ubomi benkonzo yezinto zokwakha kwaye kunciphisa iindleko zesondlo.

3. Ukusetyenziswa kwe-HPMC kwimveliso esekwe kwisamente
I-TIILE AYIDE
I-HPMC yenye yezinto ezibalulekileyo ze-teile. Kuba iifowuni zeThele zineemfuno eziphezulu zokunamathela kumhlatho, ukongezwa kwe-HPMC ukuphucula ubukhulu becala kunye ne-properges yayo, uqinisekisa ukuba iithayile zinokuzinza kwaye zingakhululeki ixesha elide emva kokulala. Kwangelo xesha, ukugcinwa kwamanzi i-HPMC kungathintela ukuqhekeka kwesamente esekwe kwi-cochemes ye-cochemes ngexesha lenkqubo yokomisa kunye nokuphucula ukuqina kwembeko.

Ukuthathwa kwenqanaba lokuzimela
Ukuziqulatha udaka olukhuselekileyo kufuna ukuba izinto ezibonakalayo zinolwazi olulungileyo ngexesha lokwakha, ngelixa zingalingani okanye zingcungcuthekise ngenxa yolwelo olugqithisileyo. Ukusetyenziswa kwe-HPMC kwi-purmation yokuziqokelela akunakuphela nje ukusebenza kwendlela yokwakhiwa kwayo ngexesha lokwakhiwa, kodwa kukuphucula ububi bayo, kodwa kukuphucula ubumbeko bayo kwaye unciphise ukuvela kwe-curble kunye ne-rock.

Ingubo yangaphantsi yamanzi
I-HPMC isetyenziswa ngokubanzi ngokubambisana kwamanzi e-Cementroof, enokuphucula ukusebenza ngokukuko kokudibana, ukuphucula ukusebenza kwayo kunye nokusebenza kwamanzi. Ukugcinwa kwamanzi kunye neempawu zokwenza ifilimu ze-HPMC kuqinisekisa ukuba ukungqubana kwamanzi kunokubangela ubume bamanzi aphezulu emva kokwakha kwaye kwandise ubomi benkonzo.

Njengesongezelelo esibalulekileyo kwiimveliso ezisekwe kwisamente, i-HPMC iphucula kakhulu i-adhesion kunye nokusebenza kwezixhobo. Ngokuphucula ukugcinwa kwamanzi, i-viscosity kunye nokungaguquguquki, kunye nokuphucula ubumbethe kwi-subsest, i-HPMC ibonakalise izibonelelo ezibalulekileyo ekusebenziseni izixhobo ezisekwe kwimo yesamente. Nokuba kusentsilweni lodaka, iingubo ze-tile okanye iingubo zangaphantsi, i-HPMC inokuphucula ngokufanelekileyo ukusebenza kunye nomgangatho wokwakha, ukwandisa indleko zenkonzo, kunye nokunciphisa iindleko zalo zokulungisa. Ke ngoko, i-HPMC iye yaba yinto engenakufumaneka kwaye ibaluleke kwizixhobo ezisekwe kwisamente.
