Iiputty kunye nezakhiwo ze-plaster usebenzisa i-MHEC

I-MHEC, okanye i-methylhydroxyethylcellulose, iyongezo yeekhemikhali ebalulekileyo esetyenziswa ngokubanzi kwizinto zokwakha. Ngokukodwa kwiingubo kunye nezinto zokugqiba ezifana ne-putty kunye ne-plaster, indima ye-MHEC ibaluleke kakhulu.

1. Ukusebenza kwe-MHEC kwi-putty

I-Putty yimathiriyeli esetyenziselwa ukuzalisa iindonga ezingalinganiyo okanye ezinye iindawo. Kufuneka ibe nokusebenza kakuhle kolwakhiwo, amandla kunye nokuqina. Ukusetyenziswa kwe-MHEC kwi-putty ikakhulu kubandakanya le miba ilandelayo: 

a. Isiphumo sokutyeba

I-MHEC inokunyusa kakhulu i-viscosity ye-putty kwaye iphucule i-fluidity yayo kunye nokusebenza kokwakhiwa. Esi siphumo sokuqina sinokunceda ukulawula ukuhambelana kwe-putty, okwenza kube lula ukufaka kunye nokugcina ubukhulu obuhle kwiindawo ezithe nkqo ngaphandle kokugrumba. Ukuqina okufanelekileyo kunokuphucula ukusebenza kwe-anti-sag ye-putty, ukwenza ukwakhiwa kube lula ngakumbi.

b. Ukugcinwa kwamanzi

I-MHEC inokugcinwa kakuhle kwamanzi, okubaluleke kakhulu ekusebenzeni kwe-putty. I-Putty ithatha ixesha elithile ukuba yome kwaye iqiniswe emva kokufakwa kwesicelo. Ukuba umswakama ulahlekile ngokukhawuleza, kuya kubangela ukuba umphezulu we-putty uqhekeke okanye ube ngumgubo. I-MHEC inokwenza ifilimu yokugcina amanzi kwi-putty kwaye inciphise izinga lokunyuka kwamanzi, ngaloo ndlela iqinisekise ukomisa okufanayo kwe-putty, ukunciphisa ukubunjwa kweentanda, kunye nokuphucula umgangatho wemveliso egqityiweyo.

c. Ukuphucula ukunamathela

I-MHEC inokuphucula i-adhesion of putty, iyenze ibambelele ngakumbi kwii-substrates ezahlukeneyo. Oku kubalulekile kuzinzo kunye nokuqina kwe-putty layer. Ukubambelela okulungileyo akunakunqanda kuphela i-putty ekuweni, kodwa nokwandisa ukuchasana kwempembelelo ye-putty kunye nokwandisa ubomi bayo benkonzo.

2. Ukusebenza kweMHEC kwigypsum

I-Gypsum yinto yokwakha esetyenziswa ngokuqhelekileyo enokumelana nomlilo kunye nemiphumo yokuhlobisa. Indima ye-MHEC kwi-gypsum ayinakuhoywa. Iimpawu zayo eziphambili zezi zilandelayo:

a. Phucula umsebenzi wokuqhuba

I-MHEC iphucula iipropati zokucubungula i-plaster, okwenza kube lula ukuxuba kunye nokusabalalisa. Ngokulungelelanisa i-viscosity kunye nokuhambelana kwe-gypsum slurry, i-MHEC inokunceda abasebenzi bokwakha balawule kangcono ubungakanani kunye nobukhulu be-gypsum esetyenzisiweyo. Oku kunenzuzo kakhulu ekuphuculeni ukusebenza kakuhle kolwakhiwo kunye ne-flatness yemveliso egqityiweyo.

b. Ukuphucula ukuxhathisa kokuqhekeka

I-Plaster ixhomekeke kwi-shrinkage cracks ngexesha lenkqubo yokuqina, enokuchaphazela ukubonakala kwayo kunye nokusebenza kwayo. Ukusebenza kokugcinwa kwamanzi kwe-MHEC kunokunciphisa ngokufanelekileyo izinga lokunyuka kwamanzi kwi-gypsum, ukunciphisa ukubunjwa koxinzelelo lwangaphakathi, ngaloo ndlela kuncitshiswe iziganeko zokuqhekeka. Ukongezelela, i-MHEC inokuphucula ukuguquguquka kwe-plaster, okwenza kube nzima ukumelana noxinzelelo lwangaphandle.

c. Ukuphucula ukuguda komphezulu

Ukusetyenziswa kwe-MHEC kwi-gypsum kunokuphucula umgangatho wayo ogudileyo kwaye wenze ukubonakala kweemveliso ze-gypsum zihle kakhulu. Umphezulu ogudileyo awunayo kuphela impembelelo engcono yokuhlobisa, kodwa inika isiseko esingcono sokunamathela kwepeyinti, eququzelela iinkqubo zokudweba ezilandelayo.

Njengesongezo sezinto zokwakha ezibalulekileyo, i-MHEC ibonisa iipropati ezininzi eziphezulu xa zisetyenziswe kwi-putty kunye ne-gypsum. Ayinakuphucula kuphela umsebenzi wokwakha, ukuphucula ukubambelela kunye nokugcinwa kwamanzi kwezinto eziphathekayo, kodwa kwakhona kuphuculwe kakhulu ukuchasana nokuqhekeka kunye nomgangatho womhlaba wemveliso egqityiweyo. Ezi zakhiwo zenze i-MHEC isetyenziswe ngokubanzi kwishishini lokwakha, ibe yinto ebalulekileyo yezinto ezifana ne-putty kunye ne-plaster. Kwixesha elizayo, ngophuhliso lwetheknoloji yokwakha kunye nokuphuculwa kweemfuno zokusebenza kwezinto, ithemba lesicelo se-MHEC liya kuba libanzi.
