Udidi lokusetyenziswa kweHydroxypropyl methylcellulose?

I-Hydroxypropyl methylcellulose yahlulwe yaba ziintlobo ezimbini: uhlobo oluqhelekileyo lwe-hot-melt kunye nohlobo olukhawulezileyo lwe-cold-water.

Ukusetyenziswa kwe-hydroxypropyl methylcellulose

1. Uthotho lweGypsum Kwiimveliso zothotho lwegypsum, ii-cellulose ethers zisetyenziselwa ukugcina amanzi nokwandisa ukuguda. Zidibene zibonelela ngesiqabu. Zinokusombulula amathandabuzo okuqhekeka kwedrama kunye namandla okuqala ngexesha lokwakha kwaye zandise ixesha lokusebenza.

2. Kwi-putty yeemveliso zesamente, i-cellulose ether idlala indima yokugcina amanzi, ukunamathela kunye nokuthambisa, ukuthintela ukuqhekeka kunye nokuphelelwa ngamanzi emzimbeni okubangelwa kukulahleka kwamanzi amaninzi, kwaye xa zidibene ziphucula ukunamathela kwe-putty kwaye zinciphisa ukwenzeka kwenkqubo yokwakha. Ukuwa, kwaye zenze ulwakhiwo lube lula ngakumbi.

3. Ipeyinti yeLatex Kwishishini lokugquma, ii-ether ze-cellulose zingasetyenziswa njengee-arhente zokwenza ifilimu, izithambisi, izihlanganisi kunye neziqinisi, ezenza ukuba zibe nokumelana okuhle kokuguguleka, ukusebenza okufanayo kokugquma, ukunamathela kunye nexabiso le-PH, kwaye ziphucule uxinzelelo lomphezulu. Ikwasebenza kakuhle xa idityaniswe nezinyibilikisi zendalo, kwaye ukugcinwa kwayo kwamanzi amaninzi kuyenza ibe ntle kakhulu ekuxubeni nasekulinganiseni.

4. I-arhente yojongano Isetyenziswa kakhulu njengesithambisi-ndlela, inokunyusa amandla okuxinana kunye namandla okucheba, iphucule uqweqwe lomphezulu, kwaye iphucule amandla okunamathela kunye nokubopha.

5. I-mortar yokugquma udonga lwangaphandle I-cellulose ether kweli nqaku igxile ekubopheni nasekunyuseni amandla, okwenza i-mortar ibe lula ukuyisebenzisa kunye nokuphucula ukusebenza kakuhle. Isiphumo sokungawi, umsebenzi ophezulu wokugcina amanzi unokwandisa ixesha lenkonzo ye-mortar, uphucule ukumelana nokufinyela nokuqhekeka, uphucule umgangatho womphezulu kwaye wonyuse amandla e-mortar.

6. Iiseramikhi zobusi Kwiseramikhi ezintsha zobusi, iimveliso zithambile, zigcina amanzi kwaye zinamandla.

7. I-Sealant, i-suture Ukongezwa kwe-cellulose ether kwenza ukuba ibe nokunamathela okuhle kakhulu komphetho, izinga lokunciphisa eliphantsi kunye nokumelana nokuguguleka okuphezulu, kwaye ikhusela idatha engaphantsi kumonakalo woomatshini, ithintela impembelelo yokuntywila kuyo yonke into yokwakha.

8. Ukuzilinganisa Ukunamathela okuzinzileyo kwe-cellulose ether kuqinisekisa ukugeleza okugqwesileyo kunye nokukwazi ukuzilinganisa, kwaye izinga lokugcina amanzi asebenzayo liyenza ikwazi ukuseta ngokukhawuleza, okunciphisa ukuqhekeka kunye nokufinyela.

9. Ukwakha i-mortar yokuplasta i-mortar Ukugcinwa kwamanzi amaninzi kwenza isamente ibe namanzi apheleleyo, kwandisa kakhulu amandla e-bond, kwaye kwangaxeshanye kwandisa ngokufanelekileyo amandla okuxinana nokucheba, nto leyo ephucula kakhulu isiphumo sokwakha kunye nokusebenza kakuhle komsebenzi.

10. I-adhesive yethayile Ukugcinwa kwamanzi amaninzi akudingi ukufunxwa okanye ukumanziswa kwethayile kunye neengqimba zesiseko, nto leyo ephucula kakhulu amandla e-bond, ixesha elide lokwakhiwa kwe-slurry, ulwakhiwo olucolekileyo nolulinganayo, ulwakhiwo olulula, kunye nokuchasana okugqwesileyo kokufuduka.

Indlela yokunyibilikisa

1. Thatha umlinganiselo ofunekayo wamanzi ashushu, uwafake kwisitya uze uwafudumeze ukuya kuthi ga kwi-85°C, uze wongeze kancinci le mveliso xa uvuselela kancinci. I-cellulose iyadada emanzini ekuqaleni, kodwa isasazeka kancinci kancinci ukuze yenze i-slurry efanayo. Pholisa isisombululo ngokushukumisa.

2. Okanye fudumeza i-1/3 okanye i-2/3 yamanzi ashushu ukuya kuma-85— okanye ngaphezulu, yongeza i-cellulose ukuze ufumane i-slurry yamanzi ashushu, uze wongeze amanzi abandayo aseleyo, uqhubeke uvuselela, uze upholise umxube ophumayo.

Ukulumkela

Ukuqina okwahlukeneyo (60,000, 75,000, 80,000, 100,000), kupakishwe kwiidrama zekhadibhodi ezifakwe ifilimu ye-polyethylene, ubunzima obucocekileyo kwidrama nganye: 25kg. Kuthintelwe ilanga, imvula kunye nokufuma ngexesha lokugcina nokuthuthwa.
