IHydroxypropyl Methylcellulose (HPMC) yi-ether ye-annoinic cellulose esetshenziswa kabanzi emkhakheni wezinto zokwakha, ikakhulukazi ku-cunmer datar.
1. Ukugcinwa kwamanzi okuthuthukile
Eminye yemisebenzi esemqoka ye-HPMC ku-Cement Jature ukuthuthukisa ukusebenza kwayo kokugcina amanzi. Uma amanzi esitsheni usimende avele ngokushesha, kuzoholela ekutheni i-hddration enganele kasimende, ngaleyo ndlela ithinta amandla nezibopho zokubopha zodaka. I-HPMC ingakwazi "ukukhiya" ama-molecule wamanzi nge-hydrophility yayo, ngaleyo ndlela kubambezele ukuhwamuka kwamanzi nokwenza ukusabela kuka-hydrate kusakhelo kuqedwe ngokwengeziwe. Ukusebenza okuhle kokugcinwa kwamanzi akugcini nje ngokuthuthukisa amandla okuqala kadaka, kepha futhi kuvimbela ngempumelelo ukuqhekeka okuminyanisayo komile.
Ukugcinwa kwamanzi kubaluleke kakhulu ezindaweni ezishisayo noma ezomile. I-HPMC ingakha ifilimu eliminyene elivikelayo endaweni eyomile yodaka ngosimende ukuvikela ukulahleka komswakama ngokweqile, ngaleyo ndlela uqinisekise ikhwalithi yezezinto zokwakha esiteji sokuqala sokomiswa.
2. Thuthukisa ukusebenza
I-HPMC inomphumela omkhulu wokuqina futhi ingathuthukisa i-viscosity nokusebenza kosimende kasimende. Ngesikhathi senqubo yokwakha, uma udaka kasimende unobumelebisi obubi nokuvunywa okunganele, kuthambekele ekunciphiseni, ukugcwala, njll., Ngaleyo ndlela kuthinta ikhwalithi yokwakha. I-HPMC ingakhuphula ukubonwa kosimende kasimende ukuze ikwenze ibe nezindawo ezinhle ze-anti-sag. Ngisho nalapho ekwakheni endaweni ebheke phezulu, kungaqinisekisa ukuthi udaka luhlanganiswe ngokulinganayo futhi lunzima ukushelela phansi.
I-HPMC ingaphinde yenze ukuthungwa kodaka kube kuhle kakhulu futhi kufane, kube ngcono i-plastiki nokusebenza kodaka, futhi wenze abasebenzi bokwakha bakhululeke kakhulu ekuphathweni nasekusebenzeni.
3. Thuthukisa amandla okubopha
I-HPMC ingathuthukisa ngempumelelo amandla eBonding omende kasimende. Amandla eBonding Omuncy Datar kungenye yezinkomba zayo ezibalulekile zokusebenza, ikakhulukazi lapho isetshenziswa ekubekeni ama-ceramic tile, amasistimu wokufaka odongeni wangaphandle kanye nezinye izikhathi ezidinga amathuba aphezulu okubopha. I-HPMC ithuthukisa ukufana kodaka ukuze izinhlayiya zensimbi zingasongelwa kangcono futhi ziboshwe ebusweni be-substrate, ngaleyo ndlela zithuthukise ukusebenza kokunamathela onke.
Amandla amahle abusayo awakwazi ukwenza ngcono ukumelana nokukhipha kodaka, kepha futhi avikele ngempumelelo izinkinga ezinjengamathayili we-ceramic kanye namathayili odonga kusuka ekuweni ngesikhathi sesakhiwo.
4. Nweba amahora okuvula
Isikhathi sokuvula sisho isikhathi lapho uCinder Data ahlala esebenza ngemuva kokwakhiwa. Ukuze babekwakhe abasebenzi, ngokufanelekile isikhathi sokuvulwa kodaka kungasiza ukuthuthukisa ukusebenza kahle kokwakha, ikakhulukazi ekwakhiweni kwezindawo ezinkulu noma izinqubo eziyinkimbinkimbi zokwakha. I-HPMC inganweba ngempumelelo isikhathi sokuvula sikasika usimende, okuvumela abasebenzi bezokwakha ukuthi basebenze kahle isikhathi eside futhi bagweme ukwehluleka okubangelwa ukulahleka kwamanzi okusheshayo kodaka.
Ekwakhiweni kwangempela, i-HPMC iqinisekisa i-hydration eqhubekayo yomamende futhi inwebe isikhathi sokusebenza sodaka ngokubambezela ukuhwamuka kwamanzi, okuthuthukisa ukuguquguquka kokwakhiwa ngezinga elithile.
5. Thuthukisa ukumelana nokuqhekeka
I-HPMC nayo ingathuthukisa ngempumelelo ukumelana nokuqhekeka kosimende. Usimende kasimende uzothola ivolumu shrinkage ngesikhathi senqubo enzima. Ikakhulu uma umswakama ulahlekelwe ngokushesha okukhulu ekuqaleni, ukuqhekeka kwe-shrinkage kungavela kalula, kuthinte ukubukeka nokuqina kwesakhiwo. I-HPMC yehlisa ngempumelelo amathuba okuqhekeka okulomile kwe-shrinkage ngokwenza ngcono ukusebenza kokugcinwa kwamanzi kodaka, ukugcina umswakama ofanayo kanye nokushisa ngesikhathi senqubo eqinile, futhi kunciphisa ukucindezela okuqinile.
6. Vimbela ukuhlukaniswa nokopha
Usimende kasimende, uma umswaki wezinhlayiya nezinhlayiya eziqinile zihlukane, kuzoholela ezinkingeni ezinjengokopha nokuhlukaniswa, okuzothinta amandla nokufana kodaka. I-HPMC ingavimbela lezi zimo ukuthi zingaveli ngokwandisa ukuthi i-viscosing ka usimende kasimende, ukuqinisekisa ukuthi izinhlayiya zosekhulile, ukugwema ukopha, nokuqinisekisa ukuthi ikhwalithi yodaka ngodaka ngemuva kokwakha i-datan iqinile.
7. Khulisa ukumelana nesithwathwa
I-HPMC ibuye ibe nomthelela othile ekuthuthukiseni ukumelana nesithwathwa kosimende kasimende. Ezindaweni ezibandayo, umswakama ku-usimende kasimende ungahle uqhwa, ubangele ukwaziswa kukhuliswe ngevolumu nokuqhekeka. Ngokwenza ngcono ukuhlangana nokugcinwa kwamanzi kodaka, i-hpmc inganciphisa ukuhlukaniswa kwamanzi angaphakathi, ngaleyo ndlela kuthuthukise ukumelana nodaka kwemijikelezo ye-freeze-thaw.
8. Khulisa ukumelana nokugqwala
I-HPMC ingaba nomthelela othile ekumelaneni nokugqwala kosimende kasimende. Ngokwenza ngcono ukuhlanganiswa kosimende kasimende, i-HPMC inganciphisa ukungenela kwemidiya ye-corlosve yangaphandle efana nama-acids, i-alkali, kanye nosawoti, ngaleyo ndlela kuthuthukise ukuqina kodaka kosimende nokwenza impilo yayo yesevisi.
9. Thuthukisa amandla acindezelayo
I-HPMC ithuthukisa ukusabela kwe-hydration ye-CEAND ngokusabalalisa ngokulinganayo amanzi, okwenza i-slurry denser, ethuthukisa amandla acindezelayo owesimate ngezinga elithile. Yize i-HPMC ngokwayo ayihlanganyeli ngokuqondile ukusabela kwe-hydration ye-CEAND, ukuguqulwa kwayo kungenza ukuthi udaka luye abe yisakhiwo sangaphakathi esizinzile ngemuva kokuqina, ngaleyo ndlela sithuthukise izakhiwo zalo ze-mehendi.
Iqhaza le-hydroxypropyllllt methylcellose ku-usimende kasimende ikakhulukazi liboniswa ekuthuthukiseni ukugcinwa kwamanzi, ukwenza ngcono ukusebenziseka, ukuthuthukisa amandla okubopha, ukunweba isikhathi esivulekile kanye nokuvimbela ukuhlukaniswa. Lezi zici zenza i-HPMC ibe yisengezo esisemqoka ku-Cement Datar. Umphumela wayo wokuguqulwa uvelele ikakhulukazi ezindaweni ezedlulele ezifana nokuma, izinga lokushisa eliphakeme, nokubanda. Ngakho-ke, ukusetshenziswa okunengqondo kwe-HPMC kungathuthukisa kakhulu ukusebenza kokwakha nokuqina kodaka ngosimende, okubaluleke kakhulu ngokwenza kahle ukusebenza kwezinto zokwakha.
