Isetyenziswe njani i-stanch ether kwi-gypsim

Isitatshi se-Ether, njengesitatshi esiguquliweyo, sisetyenziswa ngokubanzi kwi-Gypsim Abenouve ukuphucula iipropathi zayo eziqhutywa, iipropathi zokwakha kunye neempawu zokugqibela zoomatshini. I-Gypsim Adhesive sisixhobo esiqhelekileyo sokwakha esisetyenziselwa ukubhotya nokuncamathisela iiBhodi zeGypsim, izixhobo zokuhombisa, njl.

(1) Iimpawu ze-starch ether

I-starch ether yindawo enyibilikayo ye-polymer eyenziwe ngokuguqulwa kwemithombo yeekhemikhali kwenqaku lendalo. Isitatshi esiqhelekileyo sibandakanya i-Hydroxyl starch Ether, i-carboxymethy starch ether, i-stanses staines, kodwa iphucule i-stabing therches, njl.

Iimpawu zibandakanya:
Ipropathi entle yokuthambisa: I-starch Ether inamandla aqinileyo kwaye inokunyusa i-viscofity ye-gypsim ayinamathelisi, ngokwenza oko kuphuculwe iipropathi zokwakha.
Ukugcinwa kwamanzi: inokubonelela ngomthamo othile wokugcina amanzi kwimbeko, ukwandisa ixesha lokusebenza, kwaye kuthintele ukuqhekeka okubangelwa kukulahleka kwamanzi kakhulu.
Unamathengo: Ukuphucula ububi phakathi kwe-gypsim
Ukulungiswa okuguquguqukayo: Iipropathi ezinje ngexabiso lokuchithwa kunye neempawu zokubonisa i-viscosity zinokwenziwa ngokutshintsha isakhiwo sekhemikhali sesitatshi.

(2) Indlela yokusebenza ye-starch ether kwiGypsive

I-1. Iziphumo zokonwaba
Emva kokuba i-stanch Ether inyibilikisiwe emanzini, ikhonkco lepolimer lenziwe linokufaka kwaye lilungise inani elikhulu leemolekyuli zamanzi, ngaloo ndlela kunyusa ukubonakala kwenkqubo yokunamathela. Esi siphumo sokuqaqamba asincedi nje ukuphucula ukusebenza kweGypsim Abenamatheli, kodwa kunokuthintela ukuqhutywa kwinqanaba elithile, ukuqinisekisa ukufana kunye nokuzinza komntu onamanzi.

Ipropathi yokugcina amanzi ye-starch Ether ivumela i-gypsim ukubambelelane ukugcina umswakama okufanelekileyo ngexesha lokwakha, ukunqanda ingxaki yokubangelwa kukukhululwa okukhulu kwamanzi. Kwangelo xesha, ipropathi efanelekileyo yokugcina amanzi inceda inkqubo yokunyanga ye-gypsim ukubambelela, ukwenza imveliso egqityiweyo ihlala ihleli ngakumbi.

3. Ukuphuculwa kwentsebenzo yokwakha
Ngokugcina amanzi kunye nokugcinwa kwamanzi, i-starch Ether inokuphucula kakhulu ukusebenza kwe-gypsim, njengokwandisa ixesha lokusebenza (ixesha lokuvula) kunye nexesha lokwakha, ukuze abasebenzi bokwakha, ukuze abasebenzi bokwakha banokuba nexesha elingakumbi lokwenza uhlengahlengiso kunye nolungiso. Ukongeza, i-starch Ether inokuphucula ulwelo lokudibana, ukwenza ukuba kube lula ukufaka isicelo, kunye nokunciphisa ukuvela kweziphene ezinjengeebhulukhwe kunye nemingxunya yesanti.

I-4. Ukuphucula ukusebenza kwe-Bonding
Ubukho be-starch ether yonyusa amandla ama-premolecular phakathi kokuthambeka kunye nokuthathwa komhlaba, ngaloo ndlela kuphuculwe amandla akwandisiweyo. Oku kubaluleke kakhulu kwizicelo ezifuna ukunamathela okuphezulu, ezinjengeBhodi yeGyppum past kunye nokuzaliswa okudibeneyo.

(3) Isiphumo seSicelo seStanch Ether

1. Yandisa i-viscofity ye-gypsim
I-starch ether inokunyusa kakhulu i-viscofity ye-gyppum ayinamatheli U-Viskosity ofanelekileyo unokunciphisa ukungcungcutheka, ukuphucula ukusebenza kokusebenza kunye nokufana kokudibana.

2. Ixesha lokusebenza elandisiweyo
NgeePRETTE zokugcina amanzi kakuhle, i-starch ethen ingandisa ixesha lokusebenza leGypsim, ivumela abasebenzi bokwakha ukuba benze imisebenzi yokwakha ngokuzolileyo. Ixesha lokusebenza elandisiweyo linokunciphisa ireyithi yokusebenzela ngexesha lokwakha kunye nokuphucula ukusebenza kakuhle komsebenzi.

3. Ukonyuka kwamandla
Ukongezwa kwe-starch Ether yonyusa amandla okugqibela aphezulu, ukwenza isiphumo somoya oqinileyo kwaye uzinzile. Oku kubaluleke kakhulu kwiimeko ezisetyenziswa nzima kakhulu, ezinjengokulungiswa kunye nokuzaliswa kwebhodi ye-gypsam.

I-4. Ukuphuculwa kwe-fluindity kunye nokusebenza kokwakha
Ipropathi entle yeRheeology ye-starch Aben Yenza i-Gypsives Abenols ineetyiwa kunye nokusebenza okusebenzayo, ekulula ukufaka kwaye kugudileyo, ukunciphisa ubunzima kunye neziphene ekwakhiweni.

(4) Indlela yokusebenzisa i-starch

I-1. Iimfuno zenqanaba
Isixa se-starch ether ongezwe kwi-Gypsim Dheshes sihlala sincinci, ngokubanzi phakathi kwe-0.1% kunye ne-0.1% ye-0,5% (iqhezu le). Imali ethile kufuneka ilungiswe ngokwefom yefomula, yokusetyenziswa kwendalo kunye neemfuno zomsebenzi we-gypsim. Ukongeza kakhulu kunokubangela i-viscofity eninzi kwaye kuchaphazele imisebenzi yokwakha.
