Hydroxypropyl amulum Aether (HPS)etCellulose aetherare two common construction chemical additives, widely used in building materials, such as mortar, putty powder, coatings, etc. Although they have similarities in some properties, there are significant differences in many aspects such as raw material sources, chemical structures, physical properties , Application effectus et costs.
I. Rudis materia fontes et eget structure
Hydroxypropyl amulum Aether (HPS)
HPS fundatur super naturalem amulum et adeptus per etherification modificatio reactionem. Suum pelagus rudis materiae sunt frumentum, triticum, potatoes et aliis plantis. Mollis moleculis sunt composito ex GLYCOSA unitates coniunctum ab α-1,4-glycosidic vincula et parva moles α-1,6-glycosidic vincula. Post hydroxypropylation, hydroxypropyl group est in Hydrophilic Hydroxypropyl Group est in HPS Molecular structuram, dare certam crasso, aqua retention et modificatio munera.
Cellulose aether
Cellulosa aethere ex natura cellulosa, ut bombacio vel lignum. Cellulose est composito ex GLYCOSA unitates coniunctum ab β-1,4, glycosidic vincula. Commune Cellulose aether includit hydroxypropyl methylcellosa (HPMC), Methylcellulose (mc), hydroxyethyl cellulosa (HEC), etc. His componit et altius genus substituat stabilitatem et corporis proprietatibus.
II. Physica proprietatibus
Perficientur characteres de HPS
Crassis: HPS habet bonum crasso effectum, sed comparari Cellulose aether, crasso facultatem est leviter debilior.
Aqua retention: HPS moderari aqua retention et idoneam humilis ad medium range aedificium materiae.
Opus: HPS potest amplio in workability de cæmento et reducere sagging durante constructione.
Temperature resistentia: HPS valde sensitivo temperatus et valde affectus ambientium temperatus.
Perficientur characteres de Cellulose aether
Crasso: Cellulose aether habet fortis crasso effectum et potest significantly auget viscositas cæmento aut putty.
Aqua retention: Cellulose aether habet optimum aqua retention proprietatibus, praesertim in altum temperatus environments, quae extend per foramen tempus cæmento ne nimia aqua damna.
Opus: Cellulose aether est optimum in melius operis et efficaciter reducere problems ut fregisset et pulvering.
Temperature resistentia: Cellulose aether habet fortis adaptability ad temperatus mutationes et relative firmum perficientur.
III. Application effectus
Applicationem effectus estHPS
In sicco cæmento, HPS maxime ludit partes improvidus workability, meliorem aquam retention et reducendo delaination et segregationem. Est oeconomica et idoneam ad usum in missionibus cum excelsum sumptus imperium requisitis, ut Ordinarius Interior Wall Peste pulveris, pavimento adtritio cæmento, etc.
Application effectus de Cellulose aether
Cellulose aetherSunt late in altus-perficientur mortariis, lateres adhesives, gypsi-fundatur materiae et exterior Wall Nullius Systems. Et superior crasso et aqua retention proprietatibus potest significantly amplio ad vinculum vires et anti-praetermisissent perficientur de materia, et maxime idoneam ad projects, quae habent altum requisita in constructione perficientur et complevit productum qualitas.
IV. Cost et environmental praesidium
Custus:
HPS habet inferioribus sumptus et idoneam usum in pretio-sensitivo fora. Cellulosa aethere sunt relative pretiosa, sed habere optimum perficientur et sumptus-effective in postulans constructione projects.
Environmental Tutela:
Utrumque ex natura materiae et bonum environmental proprietatibus. Sed quia pauciores eget reagentia consumentur in productio processus of HPS, environmental onus sit inferior.
V. Electio basis
Euismod requisitis: si alta requisita crasso et aqua retention proprietatibus, vos should eligere Cellulose aether; Nam materiae quae sunt cost-sensitive sed requirere quaedam melioramentis in workability, vos can considerans per HPS.
Usus Scenarios: High-Temperature constructione, exterior Wall Nulla, Tile tenaces et aliis missionibus quod requirere summus perficientur firmamentum sunt magis idoneam ad Cellulose aether; Ordinarius interius murum puty aut basic cæmento, HPS potest providere frugi et practica solutions.
Hydroxypropyl starch aetheretCellulose aether Quisque habent sua commoda et ludere diversis numeribus in aedificationem materiae. Electio necessitates ad comprehendendo considerari secundum perficientur requisita, sumptus imperium, constructione environment et aliis factors de propria project ad consequi optimum usum effectus.
