I-HPMC (Hydroxypropyl Methylcellulose), njengekhemikhali ye-polymer e-soluble yamanzi ebalulekileyo, isetyenziswe ngokubanzi kwizinto zokwakha, ngakumbi kwi-putty eludongeni kunye ne-tile sement glue. Ayinakuphucula kuphela ukusebenza kolwakhiwo, kodwa ikwaphucula kakhulu umphumo wokusetyenziswa kwemveliso kunye nokwandisa ukuqina kweprojekthi.
1. Iimpawu ezisisiseko ze-HPMC
I-HPMC ngumgubo omhlophe ongenambala kwaye ongenavumba owenziwe kwiselulosi yendalo eguqulwe ngokwemichiza. Inonyibiliko olugqwesileyo lwamanzi kunye nokuncamathela. Ubume bayo beekhemikhali bunamaqela amabini ekhemikhali, i-hydroxypropyl kunye ne-methyl, inika iipropati ezizodwa:
Ukutyeba: Xa i-HPMC inyibilika emanzini, inokwenza isisombululo se-viscous kwaye yandise i-viscosity yezinto zokugquma izakhiwo kunye ne-adhesives.
Ukugcinwa kwamanzi: Kunokugcina ngokufanelekileyo amanzi kwaye kuthintele amanzi ukuba angabikho ngokukhawuleza, okunceda ukulinganisa kunye nokwakhiwa kweempawu zepeyinti.
Ukuphucula ukusebenza kolwakhiwo: yenza iingubo kunye nezinto zokuncamathelisa zibe mtyibilizi ngakumbi, unciphise ukungqubana ngexesha lokwakha, kwaye uphucule ukusebenza kakuhle kwabasebenzi.
Iimpawu zokwenza ifilimu: Uyakwazi ukwenza ifilimu efanayo ukuqinisa ukunamathela kwepeyinti.
2. Ukusetyenziswa kweHPMC kwiputty eludongeni
I-Wall putty yinto ebalulekileyo ekwakhiweni kwepeyinti. Isetyenziselwa ukugudisa udonga kunye nokulungisa iziphene eludongeni. I-HPMC idlala indima ebalulekileyo njenge-additive to wall putty.
Ukuphucula ukusebenza kolwakhiwo lweputty: Ukongeza isixa esifanelekileyo seHPMC kwiputty kunokuphucula ukusebenza kolwakhiwo lweputty. Ngenxa yempembelelo yokuqina kwe-HPMC, i-putty ilula xa isetyenzisiwe, ukunciphisa ukuxhathisa ngexesha lokwakha kunye nokuphucula ukusebenza kakuhle.
Ukuphucula ukubambelela: Impembelelo yokwenza ifilimu ye-HPMC yenza ukuba i-putty ibambelele kakuhle eludongeni, iphucula ukunamathela kwe-putty, kwaye inqande i-putty ekuweni okanye ukuqhekeka.
Ukugcinwa kwamanzi okuphuculweyo: Ukugcinwa kwamanzi kwe-HPMC kunokulibazisa isantya sokumisa i-putty kunye nokunciphisa ukwenzeka kokuqhekeka okomileyo. Ngokukodwa xa kusakhiwa kwindawo enkulu, kunokuqinisekisa ukuba umphezulu weputty kunye nomaleko wangaphakathi womile ngaxeshanye ukuphepha iintanda ezibangelwa ukomisa kwangaphambi kwexesha komgangatho womphezulu.
Ukuthintela ukuhlaliswa kunye ne-stratification: Ipropathi engqingqwa ye-HPMC inokuthintela ngokufanelekileyo ukuhlaliswa kunye ne-stratification ye-putty ngexesha lokugcinwa kunye nokuphucula ukuzinza kwe-putty.
3. Ukusetyenziswa kwe-HPMC kwi-adhesive tile Cement Cement
I-tile ye-cement glue yinto ephambili esetyenziselwa ukudibanisa iileyile kwindawo yesiseko ngexesha lenkqubo yokubeka i-tile. Ukusetyenziswa kwe-HPMC kwi-ceramic tile sement adhesive kuye kwaphucula kakhulu ukusebenza kunye nokwakhiwa kwe-adhesive ye-cement.
Ukuphucula ukubambelela: Ukongezwa kwe-HPMC kunokunyusa amandla okubambisana kwe-tile ye-cement glue, ukuqinisekisa ukuba iileyile zibambelele ngokuqinileyo kwisiseko sesiseko kunye nokuthintela iileyile ukuba zingawi. Ngokukodwa kwiindawo ezisisiseko ezigudileyo okanye ezingaqhelekanga, i-HPMC inokuphucula ukunamathela phakathi kweglu kunye nesiseko somgangatho.
Phucula ukusebenza: UkongezaHPMCkwi-tile ye-cement glue inokuphucula ukusebenza kweglue. Ngexesha lokwakha, iglue yesamente inomanzi angcono kunye nokulula ukusebenza, okuvumela abasebenzi bokwakha ukuba bafake isicelo kwaye bahlengahlengise indawo yeethayile ngokulula.
Ukugcinwa kwamanzi okuphuculweyo: Ukugcinwa kwamanzi kwisiphumo se-HPMC kubaluleke kakhulu kwi-adhesives ye-samente yethayile. Inokunciphisa isantya sokumisa i-cement slurry, ivumela iglue ukuba igcine i-viscosity efanelekileyo ixesha elide, ukuphepha ukwakhiwa okungafanelekanga okanye ukukhulula iileyile ze-ceramic ezibangelwa ukomisa ngokukhawuleza.
Ukuphucula ukuchasana nokuqhekeka: Ngethuba lokumisa inkqubo ye-samente yeglue, i-shrinkage okanye i-cracks iyakwazi ukwenzeka. Ngokuphucula i-viscosity kunye ne-film-forming properties ye-cement glue, i-HPMC inciphisa ngokufanelekileyo iingxaki zokuqhekeka okubangelwa ukucutha kwe-samente, ngaloo ndlela kuphuculwe umgangatho wokwakha jikelele.
4. Olunye uncedo lwe-HPMC kwizinto zokwakha
Ukhuseleko lokusingqongileyo: I-HPMC yinto eluhlaza kunye nokusingqongileyo, ayinayo ityhefu ngokupheleleyo kwaye ayinabungozi, kwaye ayiyi kubangela ingozi kumzimba womntu kunye nokusingqongileyo. Ngoko ke, ukusetyenziswa kwayo kwishishini lokwakha kuhlangabezana neemfuno zangoku zokusingqongileyo.
Ezoqoqosho: I-HPMC inokufikelela kwiziphumo ezibalulekileyo ngokusetyenziswa okuphantsi kwaye inexabiso eliphezulu lokusebenza. Ukongezwa kwayo kunokuphucula kakhulu umgangatho wodonga lwe-putty kunye ne-tile sement glue, ngelixa linciphisa iindleko zokuvelisa.
Ukuguquguquka okunamandla: I-HPMC inokuhambelana kakuhle nezinye izinto zokwakha ezifana nesamente, igypsum, latex, njl.
Ukusetyenziswa kweHPMCkwi-putty eludongeni kunye ne-tile ye-cement adhesive ayiphuculi nje ukubambelela, ukwakhiwa kunye nokuqina kwezinto eziphathekayo, kodwa kwakhona kuthintela ngokufanelekileyo ukuqhekeka, ukuhlaliswa kunye nezinye iingxaki. Njengokongeza kokusingqongileyo, ukonga kunye nokusebenza kakuhle, i-HPMC ibonelela ngeziqinisekiso zezinto ezikumgangatho ophezulu kwiiprojekthi zokwakha zale mihla. Njengoko ishishini lokwakha liqhubeka nokulandela ukukhuselwa kwendalo kunye nokusebenza kakuhle kolwakhiwo, ukusetyenziswa kweHPMC kuya kusasazeka ngakumbi, kudlala indima ebaluleke kakhulu ekuphuculeni ukusebenza ngokubanzi kwezinto zokwakha.
