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 ukuba ibhondi eyomeleleyo kunye nexesha elide xa 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 emincinci 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.
