Polyester resins: dzimba, maitiro, zvikamu zvebasa

Polyester resin ine nzvimbo yakakura zvakakwana. Ichi chigadzirwa chinowanikwa nekugadzirwa kwemakemikari nekuda kweimwe nzira yakaoma yekubatanidza nekugadzirisa zvinhu zvakakodzera. Kuumbwa kwepolyester resin doro, iyo inoumbwa semugumisiro wezvinhu zvekunatsa. Kuti uwane mamwe mashoko pamusoro pepolyester resins, tora pano.

Izvo izvi zvinotapira, (semuenzaniso, monoethylene glycol, diethylene, triethylene, propylene, butylene), uye glycerin, pentaerythritol, xylitol. Acids: orthophthalic, adipic, sebacic, terephthalic, manic anhydride, kusanganisira methacrylic acid uye acrylic acid. Kana zvakakosha kushandura polyester resins, pane zvingasarudzwa zvekushandisa yemafuta yemafuta nemafuta, uye resin acid.

Nekushandiswa kwechigadzirwa ichi kunobereka zvinhu zvakasiyana-siyana. Aya ndiwo mahwendefa ezvikepe, pamwe nemamwe mashoko akawanda kwavari, awa ndiwo mabhati ekugeza, surfboards, nezvimwe.

Kushandiswa kwavo kwemakemikari akadaro kwakawanikwa mumhando dzakasiyana-siyana dzekugadzira, mukugadzirwa kwemiti yakasagadzikana nemakemikari. Vakanyanyisa mukugadzirwa kwevashanyi nemitambo yemitambo, uyewo pakusikwa kwezvinhu zvakachena, somuenzaniso, vanhu vazhinji vakanzwa pfungwa yewaini yakabhati kana ye acrylic acrylic tray, nezvimwewo.

Polyester resins vane unhu hwakanaka hwemhando. Izvi zvinosanganisira:

• Kurwisana chero kupi zvayo kuchinja kwekushisa (hutongi hwehutano huri pakati pe60 kusvika ku100 degrees);
• Yakasiyana-siyana yakasimba kumirisana nemichina inoshandiswa (mushure mokunge kuoma zvakakwana kune yakakwirira kwazvo ye simba uye kuoma);
• Kurwisana kwemakemikari emakemikari (kunze kwemaindasitiri);
• Kupfeka kupikisa uye hupenyu hurefu hwehupenyu hwezvinhu zvakagadzirwa kubva kupolyester resin, nepo pakutanga maitiro maitiro hazvina kuderedzwa zvachose;
• Miti yakagadzirwa nemashoko aya inopedza kubvisa shrinkage.

Kushanda nezvinhu zvakadai sepolyester resin, hazvikonzeri kuvhiringidzika uye hazvirevi ruzivo rwakakura uye ruzivo. Chinhu chikuru ndechekuchengeta mitemo yekudzivirira yekushanda mukushanda pamwe nekugadzirisa uku uye kufungisisa mamwe maitiro. Semuenzaniso, kuitira kuti resin iwedzere panguva yekugadzirisa, uye chigadzirwa chekupedzisira chine simba rekusimba nekuvimbika kunotsanangurwa pamusoro apa, zvakakosha kushandisa zvakaoma zvakaoma.

Inofanirawo kucherechedza kuti mushure mekusanganisa resin nechokuoma kunobatsira kushanda nekukurumidza, kuitira kuti mamiriro ekugadzirisa matambudziko asingaiti. Mushure mokushandisa chinhu chacho, zvakakosha kuipa nguva yakawanda sezvinobvira kusimbisa uye kutora chimiro chaidiwa.

Kana iwe uchida kutenga zvigadzirwa zvakadaro, unofunga kufunga zvakasarudzwa kusarudza mutengesi. Anofanirwa kupa zvivako zvose zvakakodzera zvezvinhu zvake. Ipapo iwe uchava nechokwadi nezvehupamhi hwayo. Mushure mezvose, unhu hunokosha kune isu. Uye kumiti yakadaro sepolyester resins, zvinowedzera zvinodiwa zvinosimudzwa. Ndicho chikonzero iwe unoda kutora zvakanyanya nyaya yekutenga kwavo.
