Ikhompawundi edityanisiweyo yeGypsum, ekwabizwa ngokuba ludaka olomileyo okanye i-compound edibeneyo, yinto yokwakha esetyenziswa ekwakhiweni nasekulungiseni i-drywall. Ngokuyintloko iqulunqwe ngumgubo wegypsum, iminerali ethambileyo yesulfate exutywe namanzi ukwenza intlama. Olu ncamatheliso lusetyenziswa kwi-seams, iikona, kunye nezithuba phakathi kweepaneli ze-drywall ukudala indawo egudileyo, engenamthungo.
I-Hydroxypropyl methylcellulose (HPMC) yi-ether ye-cellulose ehlala idibaniswa kwi-plaster joint materials ngenxa yezizathu ezahlukeneyo. I-HPMC ithathwe kwi-cellulose, i-polymer yendalo efumaneka kwiindonga zeeseli zesityalo. Nantsi eminye imiba ephambili yokusebenzisa i-HPMC kwikhompawundi yodaka:
Ukugcinwa kwamanzi: I-HPMC yaziwa ngeempawu zayo ezibalaseleyo zokugcina amanzi. Xa idityaniswe kwikhompawundi yodaka, inceda ukuthintela umxube ukuba wome ngokukhawuleza. Ixesha elongezelelweyo lokusebenza lenza kube lula ukufaka isicelo kunye nokugqiba izinto ezidibeneyo.
Ukuphuculwa kokuqhubela phambili: Ukongezwa kwe-HPMC kwandisa ukuqhubekeka kwekhompawundi edibeneyo. Inika ukuhambelana okugudileyo, okwenza kube lula ukuyifaka kunye nokufaka kwiindawo ezomileyo. Oku kubaluleke ngakumbi ekuphumezeni iziphumo ezijongeka njengengcali.
Ukuncamathela: HPMC inceda ikhompawundi joint ukubambelela kumphezulu drywall. Inceda i-compound ibambelele ngokuqinileyo kwi-seams kunye namalungu, iqinisekisa ibhondi eyomeleleyo kunye nexesha elide emva kokuba izinto zomile.
Nciphisa ukushwabana: Izinto ezidityanisiweyo zeGypsum zithande ukushwabana njengoko zoma. Ukongezwa kwe-HPMC kunceda ukunciphisa ukucutheka kunye nokunciphisa ukubakho kweentanda ezivela kumphezulu ogqityiweyo. Oku kubalulekile ukufumana iziphumo ezigqibeleleyo nezihlala ixesha elide.
Air Entraining Agent: I-HPMC ikwasebenza njenge-arhente yokungenisa umoya. Oku kuthetha ukuba kunceda ukubandakanya amaqamza omoya amancinci kwizinto zomthungo, ukuphucula ukusebenza kwawo jikelele kunye nokuqina.
Ulawulo oluhambelanayo: I-HPMC ibonelela ngolawulo olukhulu malunga nokuhambelana kwekhompawundi edibeneyo. Oku kunceda ukufezekisa ukuthungwa okufunwayo kunye nobukhulu ngexesha lokusetyenziswa.
Kubalulekile ukuqaphela ukuba ukuqulunqwa okuthe ngqo kwezinto ezidibeneyo ze-gypsum kunokwahluka ukusuka kumenzi ukuya kumenzi, kwaye amanqanaba ahlukeneyo e-HPMC angasetyenziswa ngokuxhomekeke kwiipropati ezifunwayo zemveliso yokugqibela. Ukongeza, ezinye izongezo ezinje ngokujiya, izibophelelo kunye neeretarders zinokuqukwa kuqulunqo lokuphucula ngakumbi ukusebenza.
I-Hydroxypropyl methylcellulose (HPMC) i-cellulose ether idlala indima ebalulekileyo ekuphuculeni ukusebenza, ukunamathela kunye nokusebenza ngokubanzi kweekhompawundi ezidibeneyo ze-gypsum ezisetyenziselwa ukwakhiwa kunye nokulungiswa kwe-drywall. Iimpawu zayo eziguquguqukayo zinceda ukufezekisa ukugqiba okugudileyo kunye nokuqina kwiindawo ezomileyo.
