Water-kupezeka utoto: mitundu ndi katundu

Water-kupezeka utoto ali m'gulu la yabwino kwambiri ndi yosafuna zomangira. Chifukwa chakuti mulibe mankhwala ndiponso, ali pafupifupi palibe fungo. Water-kupezeka utoto ndi otetezeka kwambiri ndi mfundo chilengedwe view. Iwo ndi guluu wolimba kwambiri osiyanasiyana a mitundu yosiyanasiyana ya pamalo. Iwo ungagwiritsidwe ndi kutsitsi, wodzigudubuza kapena burashi utoto. Iwo ndi ntchito zabwino. Zikomo katundu awa, utoto kupezeka ali ndi udindo waukulu pakati zipangizo ntchito ❖ kuyanika padziko.

Binder particles wa nkhaniyi anamwazikana mu buku lake, pambuyo evaporation cha chinyezi iwo converge. Iwo wokhulupirika kwa mnzake pa kukhudzana, kupanga filimu. Water-kupezeka utoto ambiri kubala woyera. Kuti mtundu mukufuna, kapena za mthunzi uliwonse wa Kohler kutsatira toning utoto. Tinting zikhoza kuchitika pamanja ndipo mothandizidwa ndi makina apadera. The sangathe waukulu njira woyamba ndi vuto kugwilizana ndi kufanana zofanana kupeza mitundu chomwecho pansi kusanganikirana zotsatirazi. N'chifukwa chake onse opanga ntchito makina tinting ndi khadi (mthunzi chiwerengero, chiwerengero).

Water-kupezeka utoto anawagawa mitundu yambiri malingana binder lapansi. Malamulo yotsika mtengo ndiponso kutsatira - zipangizo zochokera PVA (polyvinyl nthochi). Iwo ali makamaka ntchito ankaudaya malinga ndi kudenga mu malo ndi chinyezi otsika. Pankhani ya wonjezerani ma polima akiliriki kusintha kukana kumva kuwawa ndi madzi kukana za tsogolo ❖ kuyanika. Styrene-butadiene binder zipangizo ndi kukana kwambiri kwa chinyezi, koma sangakhoze kulekerera kukhudzana ndi cheza ultraviolet ndi chikasu dzuwa. Chifukwa cha ichi, iwo ntchito m'nyumba mwa zipinda ndi kuyatsa yokumba.

Water-dispersive utoto akiliriki (kumene monga kumanga - yekha polima) ndi mosalekeza kwambiri. Ambiri mwa zipangizo umatulutsa lero, mumaganiza ichi, iwo nthawi zambiri ntchito ntchito kupenta.

Kujambula izi maziko tintable chabwino. Komabe, ntchito zawo n'kofunika kusankha mtundu kutenga chuma kwa Mlengi yemweyo, ndipo mwina sizikugwirizana chifukwa kusiyana machitidwe tinting. Utoto zochokera akiliriki uphwetsa msanga. Iwo bwino analekerera kukhudzana ndi dzuwa. zomangira kulola wodziwitsidwa chivundikiro zotanuka, pafupi ming'alu chabwino, chabwino analekerera ndi kusamba ndi motalika kokwanira. Pali Kusiyana, makamaka kusinthidwa kwa kupenta "moyo" mtengo. utoto amenewa kuchuluka kusinthasintha ndi zabwino nthunzi ya madzi permeability pamodzi ndi katundu madzi kufumbwa.

Kaya mtundu zakuthupi binder mu utoto umenewu ali wofooka banga: iwo kukhala opanda ntchito mwambo yozizira koopsa, kotero ndi kasungidwe kutentha zimene ziyenera chikwaniritsidwa.
