Cwaninga ekusetshenzisweni kwe-latex ye-latex evuselelayo ku-usimende-based ukuze u-moder-usezingeni

Udaka lokuzimela (i-SLM) udaka olususelwa kuso usimende olusetshenziswa kabanzi kwizicelo zasendlini nasezindaweni zangaphandle. I-SLM inempahla eyingqayizivele yokukwazi ukusabalalisa nokulinganisa ngokwayo, iqede isidingo sencwadi ebushelelezi noma ebushelelezi. Lokhu kwenza kube inketho yokonga isikhathi esiningi kakhulu samaphrojekthi amakhulu aphansi. Kodwa-ke, i-SLM yendabuko ithambekele ekuqhekekeni, i-shrinkage, kanye nokuqina. Ukubhekana nalezi zingqinamba, i-latex powder evuselelayo (i-RDP) yethulwa njengesengezo ku-SLM. I-RDP yi-polymer powder esetshenziselwa ukuthuthukisa ukuzokwenza, amandla nokuqina kwezinto zokwakha.

Izakhiwo ze-latex evuselelayo ye-latex powder

I-RDP iyimpuphu ye-polymer encoluble etholwe ngokufafaza i-aqued emulsion ye-copolymer ye-vinyl acetate ne-ethylene. I-RDP ngokuvamile ihlinzekwa njengempuphu emhlophe noma emhlophe emhlophe. Izici eziphambili ze-RDP zifaka:

1. Amandla amakhulu wokubopha: I-RDP inamandla amahle kakhulu okubopha ezigatshaneni eziningi, kufaka phakathi ukhonkolo, ngokhuni kanye nensimbi.

2. Ukumelana kwamanzi okuhle: I-RDP imelana namanzi futhi ilungele ukusetshenziswa ezindaweni ezinomswakama.

3. Thuthukisa ukuguquguquka: I-RDP ingathuthukisa ukuguquguquka komkhiqizo wokugcina, okwenza kube ngaphansi kokuqhekeka nokugoqa.

4. Thuthukisa ukusebenza: I-RDP ingathuthukisa ukusebenziseka kwe-SLM, okwenza kube lula ukuthulula nokusakazeka.

I-5. Ukuqina okuphezulu: I-RDP ingathuthukisa ukuqina komkhiqizo wokugcina, okwenza kube kancane ithambekele ekugqokeni nasekudaleni.

Ukusetshenziswa kwe-RDP ku-SLM

I-RDP ingangezwa ku-SLM ukwenza ngcono ukusebenza kwayo. Indlela i-RDP yengezwa ngayo ku-SLM ingaba nomthelela omkhulu kumkhiqizo wokugcina. Imvamisa, umthamo onconyiwe we-RDP ongezwe ku-SLM ngu-0.3% kuya ku-3.0% ngesisindo sikasimende. Ukungezwa kwe-RDP kungathuthukisa ukucubungula, amandla nokuqina kwe-SLM. Nazi ezinye izinhlelo zokusebenza ze-RDP ku-SLM:

1. Thuthukisa ukukhiqizwa: Ukungezwa kwe-RDP kungathuthukisa ukusebenziseka kwe-SLM, okwenza kube lula ukuthulula nokusakazeka. Lokhu kunciphisa ingozi yokuqhekeka nokugoqa ngesikhathi sokufaka isicelo. Ngokwengeziwe, i-RDP ingakhuphula uketshezi lwe-SLM, isize ekuzilingene kalula.

2. Khulisa amandla okubopha: I-RDP ingathuthukisa amandla okubopha i-SLM. Lokhu kusiza ukunciphisa ingozi yokudonswa noma yokuhlehlisa. Ukwenza ngcono ama-Bond Amandla futhi kuthuthukisa ubuqotho besakhiwo sohlelo oluphansi.

3. Khulisa ukuguquguquka: I-RDP ingakhuphula ukuguquguquka kwe-SLM, okwenza kube kancane ithambekele ekuqhekekeni nasekuhlobiseni. Lokhu kwandisa ukuqina komkhiqizo wokugcina.

4. Ukumelana kwamanzi okungcono: I-RDP ingathuthukisa ukumelana kwamanzi kwe-SLM. Lokhu kusiza ukuvikela isisekelo ekulimaleni komswakama.

5. Thuthukisa ukuqina: I-RDP ingathuthukisa ukuqina kwe-SLM, okwenza kube kancane ithambekele ukugqoka nokuklebhula. Lokhu kunganweba impilo yohlelo lwakho oluphansi.

Ukusetshenziswa kwe-latex ye-latex evuselelayo ku-usimende osuselwa kuso usimende osuselwa kuso usinga. I-RDP ingathuthukisa ukucubungulwa, amandla, nokuqina kwe-SLM. Izinzuzo ezisemqoka zokusebenzisa i-RDP zifaka amandla e-bond akhuphukayo, ukuguquguquka okwengeziwe, ukumelana kwamanzi okungcono, nokuqina okuthuthukile. Amandla ayo ebhondi aphezulu, ukumelana kwamanzi okuhle, ukuguquguquka okuthuthukile, ukusebenziseka okuthuthukile nokuqina okuphezulu kunikeza i-SLM ngezinzuzo ezinkulu, okwenza kube yisengezo esithandwayo semisebenzi eminingi yokwakha. Njengoba isidingo sezinhlelo ezisezingeni eliphakeme futhi ezihlala phansi zasolwandle ziyaqhubeka nokwanda, ukusetshenziswa kwe-RDP ku-SLM kungenzeka ukuthi kuqhubeke ukukhula ngokuthandwa.
