Impembelelo ye-cellulose ether ekuncipheni kweplastiki engenalo uthuli

1. Imvelaphi yophando ngesiphumo sei-cellulose etherkwiplastiki engenakuncipha kwesamente

I-mortar sisixhobo esisetyenziswa kakhulu kwiiprojekthi zokwakha, kwaye ukuzinza kokusebenza kwayo kunempembelelo ebalulekileyo kumgangatho wezakhiwo. Ukushwabana okungenaplastiki yinto enokwenzeka kwi-mortar ngaphambi kokuba iqine, nto leyo eya kubangela iingxaki ezifana nokuqhekeka kwi-mortar, nto leyo echaphazela ukuqina kwayo kunye nobuhle bayo. I-Cellulose ether, njengesongezelelo esisetyenziswa rhoqo kwi-mortar, inempembelelo ebalulekileyo kwi-mortar engenanto yeplastiki.

2. Umgaqo we-cellulose ether wokunciphisa ukushwabana kweplastiki okungenasigqubuthelo sodaka

I-cellulose ether inokugcinwa kwamanzi okuhle kakhulu. Ukulahleka kwamanzi kwi-mortar yinto ebalulekileyo ekhokelela ekuncipheni kweplastiki. Amaqela e-hydroxyl kwiimolekyuli ze-cellulose ether kunye neeathom ze-oksijini kwi-ether bonds ziya kwenza ii-hydrogen bonds kunye neemolekyuli zamanzi, ziguqule amanzi akhululekileyo abe ngamanzi abotshelelweyo, ngaloo ndlela zinciphisa ukulahleka kwamanzi. Umzekelo, kwezinye izifundo, kufunyenwe ukuba ngokonyuka komthamo we-cellulose ether, izinga lokulahleka kwamanzi kwi-mortar liyehla ngokuthe ngqo.i-methyl hydroxypropyl cellulose ether (HPMC), xa idosi iyi-0.1-0.4 (inxalenye yobunzima), inganciphisa izinga lokulahleka kwamanzi kwi-samente mortar nge-9-29%.

I-Cellulose ether iphucula iipropati ze-rheological, isakhiwo senethiwekhi eneembobo kunye noxinzelelo lwe-osmotic lwe-paste entsha yesamente, kwaye ipropati yayo yokwenza ifilimu ithintela ukusasazeka kwamanzi. Olu luhlu lweendlela ludibanisa uxinzelelo olubangelwa kukutshintsha komswakama kwi-mortar, ngaloo ndlela luthintela ukushwabana kweplastiki.

3. Isiphumo sedosi ye-cellulose ether kwi-plastic free shrinkage yesamente

Izifundo zibonise ukuba ukushwabana kweplastiki okungenasixokelelwano sesamente kuncipha ngokuthe ngqo ngokonyuka kwedosi ye-cellulose ether. Xa sithatha i-HPMC njengomzekelo, xa idosi iyi-0.1-0.4 (inxalenye yobunzima), ukushwabana kweplastiki okungenasixokelelwano sesamente kunokuncipha ngama-30-50%. Oku kungenxa yokuba njengoko idosi isanda, isiphumo sayo sokugcina amanzi kunye nezinye iziphumo zokuthintela ukushwabana ziyaqhubeka nokwanda.

Nangona kunjalo, umthamo we-cellulose ether awunakwandiswa ngokungenammiselo. Kwelinye icala, ngokwembono yezoqoqosho, ukongezwa kakhulu kuya kunyusa iindleko; kwelinye icala, i-cellulose ether eninzi inokuba nefuthe elibi kwezinye iimpawu ze-mortar, njengokuqina kwe-mortar.

4. Ukubaluleka kwempembelelo ye-cellulose ether ekuncipheni kweplastiki ngaphandle kodaka

Ngokwembono yokusetyenziswa kobunjineli obusebenzayo, ukongezwa okufanelekileyo kwe-cellulose ether kwi-mortar kunokunciphisa ngempumelelo ukushwabana kweplastiki, ngaloo ndlela kuncitshiswe ukwenzeka kwemifantu ye-mortar. Oku kubaluleke kakhulu ekuphuculeni umgangatho wezakhiwo, ngakumbi ekuphuculeni ukuqina kwezakhiwo ezifana neendonga.

Kwezinye iiprojekthi ezikhethekileyo ezineemfuno eziphezulu zomgangatho we-mortar, njengezakhiwo zokuhlala ezikumgangatho ophezulu kunye nezakhiwo ezinkulu zikawonke-wonke, ngokulawula impembelelo ye-cellulose ether kwi-plastic free shrinkage ye-mortar, kunokuqinisekiswa ukuba iprojekthi iyahlangabezana nemigangatho yomgangatho ophezulu.

5. Amathuba ophando

Nangona kubekho iziphumo ezithile zophando malunga nempembelelo ye-cellulose ether kwi-plastic free shrinkage ye-mortar, kusekho iinkalo ezininzi ezinokujongwa nzulu. Umzekelo, indlela yempembelelo yeentlobo ezahlukeneyo ze-cellulose ethers kwi-plastic free shrinkage ye-mortar xa zisebenza kunye nezinye izongezo.

Ngenxa yophuhliso oluqhubekayo lwetekhnoloji yokwakha, iimfuno zokusebenza kwe-mortar nazo ziyanda rhoqo. Kufuneka uphando olongezelelekileyo malunga nendlela yokulawula ngokuchanekileyo ukusetyenziswa kwe-cellulose ether kwi-mortar ukuze kufezekiswe isiphumo esingcono sokuthintela ukushwabana kweplastiki ngaphandle kokwenza izinto ngelixa kuthathelwa ingqalelo ezinye iimpawu ze-mortar.
