HEMC yePutty ine Yakanaka Wetting Perform

HEMC, kana Hydroxyethyl methyl cellulose, yakajairika thickener, binder, uye emulsifier inoshandiswa mumaindasitiri akasiyana siyana, anosanganisira kuvaka, zvizorwa, uye chikafu. Imwe yeakakosha zvivakwa zveHEMC kugona kwayo kukwidziridza kunyorova kwechinhu chainowedzerwa kwairi. Muchiitiko ichi, tichakurukura kuti HEMC inogona kushandiswa sei kuvandudza kunyorova kwePutty.

Putty imhando yezvinhu zvinowanzoshandiswa mukuvaka, kunyanya kuzadza maburi, makatsemuka, uye maburi mumadziro nemasirin'i. Icho chinhu chakaita senamira chinowanzo umbwa nemusanganiswa we calcium carbonate, mvura, uye inosunga mumiriri, senge latex kana acrylic. Nepo putty kazhinji iri nyore kushanda nayo, imwe yenyaya dzayo dzakajairika kusaita wetting kuita. Izvi zvinoreva kuti ine dambudziko rekunamatira kune pamusoro uye kuzadza mapundu zvinobudirira, zvichitungamira kune suboptimal kupera.

Kugadzirisa nyaya iyi, HEMC inogona kuwedzerwa kune putty kuti ivandudze kuita kwayo kunyorova. HEMC ipolymer inonyungudika nemvura inotorwa kubva ku cellulose, polima yemusikirwo inowanikwa mumadziro esero rezvirimwa. Kana yawedzerwa kune putty, HEMC inovandudza kugona kwayo kunyorova pamusoro, ichiibvumira kunamatira zvirinani uye kuzadza mapundu zvakanyanya. Izvi zvinoguma nekupera kwakapfava uye kuita kurinani kwese.

Kuti uwane huwandu hunodiwa hwekunyorova kwekuita, zvakakosha kushandisa mhando yakakodzera yeHEMC uye kutevera nzira dzakakodzera dzekusanganisa. Izvi zvinotevera zvimwe zvakakosha zvekufunga nezvazvo paunenge uchishandisa HEMC muPutty:

Rudzi rweHEMC: Kune akati wandei marudzi eHEMC aripo, imwe neimwe iine akasiyana zvivakwa uye maitiro. Mhando yeHEMC yakanakira putty inotsamira pazvinhu zvakaita sezvinodiwa kuenderana, viscosity, uye nzira yekushandisa. Kazhinji, yakaderera kusvika pakati viscosity HEMC inokurudzirwa kune putty application.

Kusanganisa maitiro: Kuve nechokwadi chekuti HEMC inogoverwa zvakaenzana mukati me putty, zvakakosha kutevedzera nzira yakakodzera yekusanganisa. Izvi zvinowanzobatanidza kuwedzera HEMC kumvura kutanga uye kuisanganisa zvakakwana usati wawedzera putty. Zvakakosha kusanganisa putty zvakakwana kuti ive nechokwadi chekuti HEMC yakapararira zvakaenzana uye kuti hapana mapundu kana masumbu.

Huwandu hweHEMC: Huwandu hweHEMC huchawedzerwa kune putty hunoenderana nezvinodiwa zvechikumbiro. Kazhinji, huwandu hwe 0.2% kusvika 0.5% HEMC nehuremu hweputty inokurudzirwa kuti iite yakakwana yekunyorova.

Pamusoro pekuvandudza kunyorova kuita, HEMC inogona kupawo mamwe mabhenefiti kana ichishandiswa mu putty. Izvi zvinosanganisira kuvandudzwa kwekushanda, kunamatira zviri nani kumusoro, uye kuderedzwa kutsemuka uye shrinkage. Pakazere, kushandiswa kweHEMC mu putty inzira inodhura yekusimudzira kuita kwayo uye kuwana kupera kuri nani.
