Udaka lokufaka ukushisa lwe-HPMC

Udaka lokufaka ukushisa lwe-HPMC lubhekisela ezintweni zokwakha ezilungisiwe laphoi-hydroxypropyl methylcellulose (HPMC)ingezwa njengesithasiselo ku-thermal insulation mortar. I-HPMC iyi-non-ionic cellulose ether enokugcinwa kwamanzi okuhle, ukuqina, ukusebenza kahle kokwakhiwa kanye nezakhiwo zokubopha. Isetshenziswe kabanzi ekwakheni i-mortar, i-putty powder, i-tile adhesive, i-thermal insulation mortar kanye neminye imikhakha.

1. Indima ye-HPMC ku-thermal insulation mortar

Inhloso eyinhloko yokwengeza i-HPMC ku-thermal insulation mortar ukuthuthukisa ukusebenza kwayo, ukugcinwa kwamanzi, ukubopha kanye nezakhiwo zokulwa nokuwa, ukuqinisekisa ukwakhiwa kwayo okulula, kanye nezakhiwo ezinhle zomshini kanye nokuqina ngemva kokuqina. Imisebenzi ethile yilena elandelayo:

1.1. Ukugcinwa kwamanzi okuqinile

I-HPMC ingathuthukisa kakhulu ukugcinwa kwamanzi kwe-mortar, igweme ukulahlekelwa amanzi ngokushesha ngesikhathi sokwakha, iqinisekise ukumuncwa okwanele kwe-samente, ngaleyo ndlela ithuthukise amandla okubopha kanye namandla aphelele e-mortar.

1.2. Thuthukisa ukusebenza kokwakha

Ngenxa yokuthambisa okuhle kanye nomphumela wokujiya we-HPMC, udaka luthambile, lubushelelezi, kulula ukulufaka nokwakha, kunciphisa isimo sokuchaphaza kanye nokuwa komlotha, futhi kuthuthukisa ukusebenza kahle kokwakha.

1.3. Ukunamathela okuthuthukisiwe

I-HPMC ingathuthukisa ukunamathelana phakathi kwe-mortar kanye nesendlalelo esiyisisekelo, igweme ukuchitheka nokugoba, futhi ithuthukise ukuzinza kwesendlalelo sokuvikela sonke.

1.4. Vimbela ukugoba

Ngesikhathi sokwakhiwa kodonga oluqondile, i-HPMC ingathuthukisa ukusebenza kodaka oluvimbela ukugoba, ukuze luhlale luzinzile ngesikhathi sokwakhiwa kodaka olujiyile futhi kungabi lula ukushelela.

2. Izici zokusebenza kodaka lokufakelwa kwe-HPMC

Ilula futhi inamandla aphezulu: Ama-aggregates alula angaphili njenge-perlite enwetshiwe kanye nengilazi ye-foam avame ukungezwa ku-mortar. Uma isetshenziswa ne-HPMC, ungqimba lokuvikela olulula nolunamandla aphezulu lungakhiqizwa.

Ukushisa okuphansi: Ukushisa kwayo ngokuvamile kuphakathi kuka-0.045 no-0.065 W/m·K, okuvimbela ngempumelelo ukufudumala futhi kuthuthukise ukusebenza kahle kwamandla kwezakhiwo.

Ukumelana nesimo sezulu okuhle: Ngaphansi kwesenzo se-HPMC, ukuqina nokumelana nokuqhekeka kwe-thermal insulation mortar kuyathuthuka, futhi ingakwazi ukuzivumelanisa nezinguquko zesimo sezulu ezahlukahlukene.

Ukuvikelwa kwemvelo kanye nokungabi nobuthi: I-HPMC iyinto eluhlaza futhi enobungani nemvelo, ehambisana nezinto ezingaphili njengesamente nesihlabathi, futhi ayikhiphi izinto eziyingozi.

3. Inkambu yesicelo

Udaka lokuvikela ukushisa lwe-HPMC lusetshenziswa kabanzi emikhakheni yohlelo lokuvikela udonga lwangaphandle, ukuvikela udonga lwangaphakathi, ukuvikela uphahla, njll. kwezakhiwo ezahlukahlukene. Lufanelekela kakhulu amaphrojekthi okuvuselela okonga amandla, izakhiwo ezisezindaweni ezibandayo, izakhiwo zomphakathi, njll., okunomthelela omkhulu ekongeni amandla kwesakhiwo kanye nenduduzo.

4. Izinyathelo zokuqapha zokwakha

Isilinganiso esifanelekile: Udaka lokuvikela ukushisa lwe-HPMC kufanele lulungiswe ngokunembile ngokwezidingo zomklamo kanye nezimo zokwakha, futhi inani le-HPMC kufanele lilawulwe ngokuvamile phakathi kuka-0.2% no-0.5% (ngesisindo sempuphu eyomile).

Hlanganisa ngokulinganayo: Uma uvuselela, izinto ezomile kufanele zixutshwe ngokulinganayo kuqala, bese kungezwa amanzi bese kuhlanganiswa ukuze kube nokuvumelana okufanayo, bese kuvuselelwa futhi ngemva kokuma imizuzu embalwa.

Ukulawulwa kwendawo yokwakha: Gwema ukwakha endaweni enokushisa okuphezulu noma enomoya ukuze uvimbele umswakama we-mortar ukuthi ungashisi ngokushesha futhi uthinte umphumela.

Ukwelashwa kwesisekelo: Isisekelo kufanele sihlanzeke, singabi namafutha nothuli oluxegayo, futhi simanziswe uma kudingeka ukuqinisekisa ukubophana okuhle.

Ukulawulwa kobukhulu bokwakha: Ubukhulu bokuplasta ngakunye akufanele bube bukhulu kakhulu, ngokuvamile bulawulwe ngaphakathi kuka-1.5cm, futhi ukwakhiwa kwezingqimba ezijiyile kufanele kwenziwe ngamaqoqo ukuvimbela ukuqhekeka nokugoba.

Udaka lokuvikela ukushisa lwe-HPMC, njengezinto zokwakha ezonga amandla ezisebenza kahle kakhulu, ihlanganisa ukuvikela ukushisa, ukuvikela ukushisa, ukwakhiwa okulula, ukuvikela okonga kanye nemvelo, futhi isetshenziswa kabanzi ezakhiweni zesimanje eziluhlaza. Ukwengezwa kwe-HPMC akugcini nje ngokuthuthukisa ukusebenza okuphelele kodaka, kodwa futhi kuqinisekisa ngempumelelo ikhwalithi yokwakha kanye nokuqina kobunjiniyela. Kuyindlela ebalulekile yobuchwepheshe yokukhuthaza ukongiwa kwamandla esakhiwo kanye nokwakhiwa kwekhwalithi ephezulu. Esikhathini esizayo, ngokuthuthukiswa okusheshayo kwezakhiwo eziluhlaza, udaka lokuvikela ukushisa lwe-HPMC luzodlala indima ebaluleke kakhulu ohlelweni lokonga amandla lwesakhiwo.
