hpmc rdp inoshandiswa muSimende Render & Plaster EIFS & ETICS
JINJI® HPMC ine zvivakwa zvakasiyana zvinoita kuti ishande uye ifarirwe kuEIFS&ETICS.
Thermal insulation board system, kazhinji inosanganisira ETICS (EIFS) (External Thermal Insulation Composite System / Exterior Insulation Finish System), kuitira kuchengetedza mutengo wekupisa kana kutonhora kwesimba, yakanaka yekubatanidza dhaka inofanirwa kuve: nyore kusanganisa, nyore kushanda. , banga risina tsvimbo; Zvakanaka anti-kurembera maitiro; Yakanaka yekutanga adhesion uye mamwe maitiro. Iyo plaster dhaka inoda kuva: nyore kubvongodza, nyore kuparadzira, banga risiri tsvimbo, nguva yekukura kwenguva refu, kugona kunyorova kwejira remambure, kwete nyore kuvhara uye humwe hunhu. Zvinodiwa zviri pamusoro zvinogona kuwanikwa nekuwedzera akakodzera cellulose ether zvigadzirwa seHydroxypropyl Methyl Cellulose (HPMC) mudhaka.
Yedu HPMC cellulose zvigadzirwa uye RDP chigadzirwa chinopa zvinotevera kuvandudzwa kuEIFS:
• Kuvandudzwa kwesimba rekunamatira uye kushanduka: cellulose ine yakanaka thickening kushanda uye lubricity, iyo inogona kuvandudza simba rekunamatira uye kushanduka kweEIFS adhesive.
• Kuchengetedzwa kwemvura kwakawedzera uye nguva yekushanda yakawedzerwa: kuderedza zvakanyanya kurasikirwa kwemvura mukutora substrates mukuumbwa. Iko kugona kuchengetedza mvura kweselulosi zvakare inosimudzira zvakanyanya kusimba kwekunamatira kweEIFS yekunamatira. Izvi zvinodaro nekuti vanosunga vane nguva yakakwana ye hydration uye panguva imwechete havarasikirwe nemvura.
• Optimized chigadzirwa kuenderana uye rheology: cellulose yakakosha kiyi yekugadzirisa kwakakodzera kuenderana mumadhaka matsva. Kuenderana kwakakodzera kunoita kuti purasita nyowani ibatanidzwe zvakanaka pamadziro pamwe nekuita kuti nzvimbo dzakapfava uye dzishandiswe zviri nyore pasina kunzwa kwekunamira. Iyo aqueous solution yeMelaColl isiri Newtonian system, uye zvimiro zvemushonga wayo zvinonzi thixotropy.
• Kuvandudza hydrophobicity: Mushure mekuwedzera cellulose, iyo hydrophobicity yeEIFS yakagadziridzwa, kudzivirira kwemvura kunowedzera zvakanyanya.
• Kuvandudzwa kwekushanda: Kuenzanisa zviri nani uye kuderedza kunamatira kwe cellulose kunogona kushandiswa nyore nyore kune EIFS adhesives, iyo iri nyore kushanda nekuvaka, uye inogona kuvandudza zvakanyanya kushanda kwekuvaka.
• Kuvandudza mashandiro ekuputira nesimba rakanakisa rekutanga: cellulose inosanganisa kubatana kwepolymer zvinhu uye kusimba kweiyo inorganic zvinhu. Ivo vanogona kuve nechokwadi chekusimba kwekutanga kwedhaka uye zvimwe zvakakosha zvivakwa zvinodiwa kuEIFS uye kuvaka kutsva.
• Kuramba kwakanaka kwemvura, kugarisana kwakanaka nezvigadzirwa zvakajairika: cellulose inoderedza zvakanyanya kurasikirwa kwemvura mukutora substrates mukuumbwa. Iko kugona kuchengetedza mvura kweselulosi zvakare inosimudzira zvakanyanya kusimba kwekunamatira kweEIFS yekunamatira. Izvi zvinodaro nekuti vanosunga vane nguva yakakwana ye hydration uye panguva imwechete havarasikirwe nemvura.
• Ratidza simba rakakwirira, kunamatira kwakasimba, uye alkali kuramba: cellulose ine kuchengetedza kwakanaka, kuwedzera pfuma, Stable makemikari ehupfumi zvinobudirira kuramba alkali kurwisa.
