Ukunyuka kokuqina kunye nokuxhathisa ukuqhekeza kwizixhobo ezisekwe kwi-HPMC

Intshayelelo
Izinto ezisekwe kwizixhobo zesamente zibalulekile ekwakheni, ukubonelela ngengqibelelo ebalulekileyo yezakhiwo, iibhlorho kunye nezixhobo. Nangona kunjalo, ezi zixhobo zithambekele ekuqhekezeni nasekuqaliseni imiba yomoya ngenxa yezinto ezahlukeneyo zokusingqongileyo kunye nezixhobo. Umdibaniso wezongezo kubaxumisileyo yesamente sisicwangciso esiliqili sokuphucula iipropathi zabo. I-HydroxyPOpyl Methylcelceltulose (HPMC) ivele njengesongezo esibonakalayo sokuphucula ukusebenza kwezinto ezisekwe kwisamente.

Iindlela zesenzo
I-HPMC sisisele i-theyser i-theymer eyaziwa ngokuba kukugcinwa kwayo amanzi, ukuphucula i-viscofity, kunye neempawu zokwenza ifilimu. Xa yongezwa kwizixhobo ezisekwe kwisamente, i-HPMC ichaphazela inkqubo ye-hydration, isakhiwo se-pore, kunye nokwenziwa kweMatrix kwi-Matrix ngeendlela ezininzi:

Ukugcinwa kwamanzi kunye nolawulo lwe-hydmc lolawulo: I-HPMC ixhasa ukugcinwa kwamanzi kwi-qumente yokudityaniswa, ebaluleke kakhulu kumbane ofanelekileyo we-sundeles. I-hydration eyaneleyo ibalulekile ekuqulunweni kwe-calcisum ye-caldicate hydrate (CSH) ijeli, umbizi ophambili onika amandla amandla alo. Ngokugcina amanzi, i-HPMC iqinisekisa ukuba i-hydration iyaqhubeka ixesha elide, ekhokelela kwi-demerser nangaphezulu.

Ukulungiswa kwe-Viscosity: ukongezwa kwe-HPMC yonyusa i-viscosity yesamente inamathisele kunye nokuzinza komxube. Oku kuyingenelo ikakhulu ekunciphiseni ukwahlulwa kunye nokopha, apho amanzi kunye namasuntswana amahle ahlukile kumxube ophambili. Umxube ozinzileyo uqinisekisa ukusasazwa kwe-theatiments, enegalelo kwinto eyomeleleyo nengahambelaniyo.

Ukuqulunqwa kwefilimu kunye nokulungiswa kwe-Pore Le filimu inokubhula i-microcracks kwaye iphucule i-tecing yezinto ezibonakalayo. Ukongeza, i-HPMC iphembelela imeko ye-pore ngokunciphisa i-carellary parosity kunye nokuphuculwa kobungakanani be-Poll. Isakhiwo se-denser pore sinciphisa ukungangqinelani, ngaloo ndlela kuphucule ukungaxhathisi kwizinto ezifana nezomkhenkce, ukuhlaselwa kwekhemikhali, kunye nokuhlaselwa kwekhemikhali, kunye nokuhlaselwa kwekhemikhali kunye nokuhlaselwa kwekhemikhali, kunye nokusetyenzwa kwekhemikhali, kunye nokuhlaselwa kwekhemikhali, kunye nokuhlaselwa kwekhemikhali kunye nokuhlaselwa kwekhemikhali, kunye nokugcinwa kwekhemikhali, kunye nokuhlaselwa kwekhemikhali, kunye nokuhlaselwa kwekhemikhali, kunye nokugcinwa kwekhemikhali, kunye nokuhlaselwa kwekhemicomi.

Izibonelelo ze-HPMC kwizixhobo ezisekwe kwiSamente
Ukufakwa kwe-HPMC ibe zizibonelelo ezisekwe kwizibonelelo zesamente ibonelela ngezibonelelo ezininzi eziphawulekayo, ngokuyintloko ijikeleze ukuqina okuphuculweyo kunye nokunganyangeki:

Ukunyuka kokuqina: Isakhono se-HPMC sokugcina amanzi hydration kunye nokulawula ifuthe ngokuthe ngqo ifuthe lokuthambisa kwexesha elide kwizixhobo ezisekwe kwimo yesamente. Ngokuqinisekisa ukuba i-hindority epheleleyo kunye nokunciphisa amandla, izixhobo ze-HPMC ezibonisa ukuphuculwa kokungavisisani kweenkqubo ezahlukeneyo eziluhlaza, i-alkali -ilica rection (i-asr) ye-ion ingenela. Eli moya inyukayo iguqulela kubomi beenkonzo ezinde kwaye incitshiswe iindleko zokulungisa izinto.

Ukunganyangeki kokuqhekeka kwe-rack: Ukuqhekeka kwezinto ezisekwe kwisamente kungenzeka ngenxa yeplastiki yeplastiki, i-shrinking yomisa, uxinzelelo lobushushu, kunye nemithwalo yoomatshini, kunye nemithwalo yoomatshini. I-HPMC inceda ukunciphisa le micimbi ngokugcinwa kwayo kwamanzi kunye nezinto ezenziweyo zefilimu. Ngokugcina imixholo eyaneleyo ngexesha lokunyanga, i-HPMC inciphisa umngcipheko weplastiki shrinkige. Impembelelo yayo ekunciphiseni ubungakanani be-pore kunye nokuphucula i-Thecubility ikwathetha ukuba izinto ezibonakalayo zinokufumana kwaye zisasaze uxinzelelo, ukunciphisa amathuba okuqhekeka kwe-rack.

Ukuphuculwa kwepropathi yokuphuculwa kunye neepropathi zezicelo: Ukuguqulwa komxube we-viscofity yi-HPMC iququzelela ukuphatha ngokuthe kratya nokusetyenziswa kwezinto ezisekwe kwisamente. Oku kubaluleke kakhulu kwiindlela zokwakha apho ukusetyenziswa kokufumana i-NECE kunye nesantya sesantya sesantya sibalulekile. Ukwazi kukaHPMC ukuthintela ukwahlula kunye nokopha kuqinisekisa ukuba umxube uhlala uguquguqukayo kwaye unekhogethi, ebaluleke kakhulu ekufezekiseni ingqibelelo kunye nengqibelelo ekumgangatho ophezulu kunye nokugcina ingqibelelo.

Izicelo ezisebenzayo
I-HPMC isetyenziswa kwiimveliso ezahlukeneyo zesamente kunye nokusetyenziswa, ukuzuza nganye kwiipropathi zayo ezizodwa:

Ukufa kunye nokubrotha: Kwindlela yokudakasa, i-HPMC iphucula ukusebenza, i-adhesion, kunye nokunganyangeki. Ezi ndawo zibalulekile ekufezekiseni iindawo ezigudileyo, ezihlala ziqinileyo kwizibini zangaphakathi nangaphandle.

I-quatuds zokuzilinganisa: i-HPMC iphucula iipropathi zokuhamba kunye nokuzinza kweendlela zokuzimela, ukuqinisekisa iyunifomu, i-crack-free. Oku kuyingenelo ikakhulu kwizicelo zomgangatho apho inqanaba kunye nokugqitywa okwenzileyo kuyafuneka.

Ababukeli beTyile: I-HPMC ixhasa i-adhesion kunye nexesha elivulekileyo le-tiles, ukubonelela ngexesha elaneleyo lokusebenza kunye neempawu ezinamandla ezibandayo. Oku kukhokelela ekuqinisekiseni kwaye kuxhathise uxinzelelo lwe-shear, olunokubangela iithayile ukuze ziqhekezwe okanye zihento.

Izixhobo zokulungisa: Ukulungisa izifakelo kunye nokukhula, i-HPMC inegalelo ekusebenzeni okungcono kunye nokuncitshiswa komhlaba, ukuqinisekisa ukuba ukulungiswa kuyahlala kwaye kuqhekezwa. Oku kubalulekile ukubuyisela ingqibelelo yezakhiwo ezonakeleyo.

I-Shotcrete kwaye itshizwe ikhonkrithi: i-HPMC iphucula ubumbano kunye ne-adhesion ye-shorcrete, ukunciphisa i-rebaund kunye nokuqinisekisa ubudlelwane obuqinileyo kunye nomhlaba onamandla. Oku kubaluleke kakhulu ekucoleni nasekwakhiweni nasekuhlaleni kokuqina apho ukuqina komgangatho kubaluleke kakhulu.

Ukufakwa kwe-HydroxyPOpyl Methylcelcelulose (HPMC) kwizinto ezisekwe ngokusesikweni kukuphucula ukuqina kwabo kunye nokuchasana nokuqhekeka. Ngokuphucula ukugcinwa kwamanzi, ukuguqula i-vitcosity, kunye nokwenza iifilimu eziguquguqukayo kwi-quetrix matrix, i-HPMC ijonge imiba ephambili enxulumene nokusasazwa kwe-hydration, i-surusity, kunye nokusasazwa koxinzelelo. Olu phuculo lukhokelela kwizixhobo ezihlala ixesha elide, zichasene nokunganyangeki, kwaye kulula ukusebenza nazo, eziguqulela kwizakhiwo ezihlala ixesha elide kunye nezinto ezinokuthenjwa. Njengoko ishishini lokwakha liyaqhubeka nokufuna iindlela zokuphucula ukusebenza kunye nokuhlala kwezinto ezisekwe kwizinto, i-HPMC iphume njengesongezo esixabisekileyo sezibonelelo ezibanzi kunye nezicelo.
