Lub teeb yuag qhob ntxiv | Kev Ua Haujlwm Siab Ua Foaming Cov Neeg Sawv Cev Rau Cov Khoom Siv Ntawm Tes
Foaming agent refers to all surface-active substances whose solutions can produce a large amount of foam through physical methods (stirring, compressed air, etc.) or chemical reactions under specific conditions. Foaming agent has high surface activity, can effectively reduce the surface tension of the liquid, and arranges the two-electron layer on the surface of the liquid film to surround the air, forming bubbles, and then developing a foam by a single bubble. The essence of the foaming agent is its surface activity. Because of the intense surface activity of the protein itself, it is possible to develop a foaming agent for the protein. When the protein is hydrolyzed, the large protein molecules of the longer peptide chain become a mixture of short-chain soluble small and medium molecules. After dissolving in water, it can form a colloidal solution with specific viscosity. The carboxyl, hydroxyl and other hydrophobic groups such as extended carbon chain hydrocarbon groups, as well as the asymmetry of the molecule, reduce the surface tension and promote the formation of the interface.
The peptide chains of these small and medium molecules stretch at the interface, the strong hydrogen bonding between the intergroup forms a flat protective net, which strengthens the interface, which promotes the formation and stability of the foam. Incomplete hydrolysis of proteins is a crucial factor in foam formation and stability. Compared with traditional physical foaming agents, chemical foaming agents, and synthetic surfactant foaming agents, Cov tshuaj ua npuas protein-based tam sim no yog ib hom tshuaj ua npuas siab uas muaj kev ua tau zoo dua thiab muaj kev cia siab rau kev tsim kho zoo dua.. Raws li kev tsim kho dav dav,, nws tau siv ntau dua nyob rau xyoo tsis ntev los no.. Txawm hais tias tus nqi siab,, nws tseem raug lees txais los ntawm kev lag luam vim nws ua tau zoo heev,, yooj yim tau txais cov khoom siv raw,, thiab kev tiv thaiv ib puag ncig..
Cov tshuaj ua npuas siv rau dab tsi? ua npuas ncauj pob zeb?
(1) Cov tshuaj ua npuas los ntawm nroj tsuag.
Cov hom tseem ceeb ntawm cov tshuaj ua npuas los ntawm nroj tsuag yog ob pawg tseem ceeb ntawm tshuaj yej saponin thiab saponin.. Yog hais kom meej,, cov khoom tseem ceeb ntawm ob hom tshuaj ua npuas no rau pob zeb tsis yog protein tab sis zoo ib yam li cov tshuaj ua npuas uas yog tshuaj qub.. Muaj qhov txawv loj piv rau qhov no.. Besides, the main ingredients of these foaming agents are from plants, so they are still classified as plant protein foaming agents. Due to sufficient raw materials, the production and application of these two types of cement foaming agents have reached a considerable scale.
Plant-based cement foaming agent uses high-quality natural plant polymer materials as raw materials and is made through a series of complex chemical reactions. The product is a pale yellow pure transparent oily liquid. Insensitive to hard water, non-toxic, odorless, no sediment. PH value is neutral, non-corrosive cement, hlau, and does not pollute the environment. The foaming agent has storage resistance, is not easy to deteriorate, has excellent foaming performance, is rich in foam, and is relatively stable. The practical application of the foaming agent to produce foam cement has the advantages of low consumption, low cost, and durable quality. It is widely used in floor heating decoration projects and roof insulation decoration projects, which can significantly save construction costs.
(2) Protein-based foaming agent
The performance of an animal protein-based foaming agent is comparable to that of plant protein foaming agent, and the foaming ability and foam stability are generally equivalent.Animal protein-based foaming agents are mainly divided into three categories: hydrolyzed animal hooves, hydrolyzed waste animal hair, and hydrolyzed blood gel. The animal cement foaming agent is selected from animal keratin and is prepared through a series of hydrolysis reactions, dissolution, dilution, filtration, and high-temperature shrinkage. Cov khoom no yog kua kua xim av tsaus uas muaj tsawg impurity, ua rau tsw ntxhov siab heev, zoo sib xws, zoo ruaj khov, ua tau yooj yim, thiab ruaj khov ua npuas. Vim muaj zog thiab ruaj khov ntawm qhov chaw ua npuas uas tsim los ntawm cov tshuaj ua npuas, cov cement ua npuas uas tsim los ntawm cov tshuaj ua npuas muaj kev kaw ywj pheej, thiab cov npuas tsis sib txuas nrog cov npuas. Cov khoom ua npuas muaj kev tiv thaiv permeability zoo heev. Nws cov cement ua npuas ib zaug tuaj yeem ncav tau tshaj 1.5m tsis poob, uas haum rau kev tsim cov pob zeb ua npuas ncauj, cov vaj huam sib luag pob zeb nyias, thiab phab ntsa faib.
qhov tsis zoo ntawm cov tshuaj ua npuas tsiaj cement
Vim txoj kev tsim khoom nyuaj, tus nqi khoom siab. Cov tshuaj ua npuas muaj peev xwm ua npuas tsawg dua cov tshuaj ua npuas hauv nroj tsuag, thiab nplaum siv rau kev noj ntau dua. Muaj ib qho tsw ntxhiab tshwj xeeb thaum siv, thiab nws yuav maj mam ploj mus tom qab hloov ua nplaum nplaum.
Cie-China.org yog tus thawj coj ua npuas ncauj qhob ntxiv muab cov pob zeb ua npuas ncauj ua npuas ncauj, superplasticizer,Ua npuas ncauj qhob lub zog enhancer rau lub teeb yuag pob zeb, CLC blocks. Yog tias koj tab tom nrhiav foaming tus neeg sawv cev, thov koj xav tias dawb rau tiv tauj peb.
