Umphumela we-latexr powder kanye ne-cellulose ekusebenzeni kodaka oluhlanganisiwe olomile

Ama-Admixtures adlala indima ebalulekile ekwenzeni ngcono ukusebenza kodaka oluhlanganisiwe omile. Lokhu okulandelayo kuhlaziya futhi kuqhathaniswa nezinto eziyisisekelo ze-latexr powder kanye ne-cellulose, futhi kuhlaziye ukusebenza kwemikhiqizo yodaka exutshwe nodaka kusetshenziswa ama-admixtures usebenzisa ama-admixtures.

I-redisperible latex powder

I-latexr evuselelayo ye-latexr icutshungulwa ngomishini wokufafaza we-emulsion ekhethekile ye-polymer. I-latexr yomisiwe ye-latexr yizinhlayiya ezithile eziyi-80 ~ 100mm zahlangana ndawonye. Lezi zinhlayiya zincibilika emanzini futhi zakha ukusakazwa okuzinzile zikhudlwana kunezinhlayiya zangempela ze-emulsion, ezakha ifilimu ngemuva kokuphelelwa umoya nokoma.

Izinyathelo ezihlukile zokuguqulwa zenza i-latex tablex ye-latex inezakhiwo ezihlukile njengokumelana kwamanzi, ukumelana kwe-alkali, ukumelana nesimo sezulu kanye nokuvumelana nezimo. I-latexr powder esetshenzisiwe ngodaka ingathuthukisa ukumelana nomthelela, ukuqina, ukuphefumula, ukukhululwa, amandla okubumbana, ukumelana kwamandla, ukuqina kwamandla, ukunqanda kwamandla, ukuncipha kwamanzi

I-Cellulose Ether

I-Cellulose Ether yigama elijwayelekile lochungechunge lwemikhiqizo ekhiqizwa ukusabela kwe-Alkali Cellulose kanye ne-ejenti ethembisa ngaphansi kwezimo ezithile. I-Alkali Cellulose ithathelwa indawo ama-ejenti ahlukile aphelelisayo ukuthola izitha ze-cellulose ezihlukile. Ngokusho kwezakhiwo ze-Ionization zokufakaza kwabanye, ama-cellulose asher angahlukaniswa izigaba ezimbili: ionic (njenge-carboxymethyl cellulose) ne-nonic (njenge-methyl cellulose (efana ne-methyl cellulose). Ngokusho kohlobo lwe-substituent, i-cellulose ether ingahlukaniswa i-monoJe (njenge-methyl cellulose) futhi i-ether exubile (efana ne-hydroxypropylylyl methyl celtule). Ngokusho kwe-soubity ehlukene, ingahlukaniswa inyumbazane yamanzi (efana ne-hydroxyethyl cellulose) kanye ne-organic solvent-soluble (njenge-ethyl cellulose (enjenge-ethyl clulsule), futhi i-cellulose enamanzi ihlukaniswe ngohlobo olusheshayo kanye ne-surface yaphathwe uhlobo lokuchitheka okubambezelekile.

Indlela yokwenza kwesenzo se-cellulose ether ngodaka kungokulandelayo:

. wokwakha.

izinkuni fiber

I-Wood fiber yenziwa ngezitshalo njengezinto eziphambili eziluhlaza futhi icutshungulwe ngochungechunge lobuchwepheshe, futhi ukusebenza kwalo kwehlukile kwaleyo ye-cellulose ether. Izakhiwo eziphambili yilezi:

. Kepha ayinakho ukugcinwa kwamanzi okuphezulu kwe-cellulose ether.
