Kuongororwa kwemhando yepamusoromishonga ye phenolic molding(yakagadzirwa ne phenolic resin matrix ine zvinhu zvinozadza, zvinogadzirisa kupisa, mafuta, nezvimwewo, zvinonyanya kushandiswa pakuumba compression) inofanira kufukidza mativi makuru anosanganisira chitarisiko, mashandiro ekugadzirisa, hunyanzvi hwemuviri nehwemakanika, hunyanzvi hwekupisa, uye kuramba kwemakemikari kuti ive nechokwadi chekuti zvinodiwa pakuumba zvinoenderana nezvinodiwa uye mashandiro echigadzirwa. Zvinhu zvakakosha zvekuongorora uye zvekufunga nezvazvo ndeizvi:

Kuonekwa Kwepakutanga uye Kuongorora Kwemhando Yekuona

Chitarisiko chinoshanda sechiratidzo chekuongorora mhando yekutanga, zvichiratidza zvakananga kufanana kwekusanganiswa kwezvinhu zvakabikwa uye pelletization (kana kugadzira upfu) panguva yekugadzira. Zvinhu zvekuongorora zvinosanganisira:

Ruvara uye Kufanana

Zvinodiwa: Zvigadzirwa zviri mukati meboka rimwe chete zvinofanirwa kuratidza ruvara rwakafanana pasina musiyano unooneka wemavara (zvinogoneka kuburikidza nekuenzanisa nemifananidzo kana machati emavara akajairwa kana kuyerwa kwehuwandu uchishandisa mita yemusiyano wemavara).

Kukosha: Kuchinja kwemavara kunogona kubva mukusiyana kwe resin batch, kusawirirana kwe filler dispersion, kana kushanduka kwekushisa kwe processing, zvichikanganisa kuenderana kwekuona kwechigadzirwa chekupedzisira.

Mamiriro eGranule/Upfu

Magranules: Ongorora chimiro chakatenderera, kusavapo kwekuungana kana kutyoka (chiyero chekutyoka chinofanira kuva ≤ kukosha kwakatsanangurwa, kazhinji ≤3%), uye kugoverwa kwehukuru hwezvikamu zvakafanana (zvinosimbiswa kuburikidza nekuongorora kwakajairwa kwesefa; semuenzaniso, chikamu che20-60 mesh chinofanira kusangana nezvinodiwa nemakambani).

Upfu: Husina mapundu kana zvinhu zvisina kuchena (semuenzaniso, tsvina yesimbi, mapundu efaibha). Edza uchishandisa skrini ye100-mesh; masara emvura anofanira kunge ari ≤0.5%.

Kusachena uye Zvisina Kunaka

Ongorora nemaziso kana negirazi rinokudza. Kusachena kwakadai sesimbi, matombo, kana mapundu asina kupararira eresin hazvibvumirwi. Nzvimbo dzegranule/hupfu dzinofanira kunge dzisina mavara emafuta kana mavanga emould (kudzivirira mabubbles kana delamination panguva yekuumba).

Kuongororwa Kwekushanda Kwekugadzirisa

Kushanda kwekugadzirisa kwe phenolic molding compounds kunosarudza zvakananga nyore kwekumanikidzwa kwe compression molding uye mwero wegoho rechigadzirwa. Zvinhu zvekuongorora zvepakati zvinosanganisira:

1. Kuyerera Kwemvura (Hunhu Hwekuyerera Kwemvura)

Nzira Yekuedza: Kazhinji Nzira yeKureba Kwekuyerera Kwemuchadenga (pa GB/T 14049-2008 “Makemikoro Ekugadzira Phenolic"). Isa mushonga wekuumba muchimiro chespiral patembiricha yakatarwa (semuenzaniso, 160-180°C) uye kumanikidzwa (semuenzaniso, 5-10 MPa), wobva wayera hurefu hwespiral inoumbwa nekunyunguduka kuri kuyerera.

Zvinokosha pakusarudza: Kutsauka kwehurefu hwemvura mukati mechikamu chimwe chete kunofanira kuva ≤±10%. Makoshero chaiwo anofanirwa kuenderana nechimiro chechigadzirwa (zvigadzirwa zvakaoma zvine madziro matete zvinoda kuyerera kwakanyanya, nepo zvigadzirwa zvine madziro makobvu zvichida kuyerera kwepakati kudzivirira kuzara).

Kukosha: Kuyerera kwakaderera zvakanyanya kunogona kukonzera kuzadza kusina kukwana kana kuti maburi emakona muzvigadzirwa; kuyerera kwakawandisa kunogona kukonzera kupenya kana kuwanda, zvichiwedzera mari yekugadzirwa mushure mekugadzirisa.

2. Kukurumidza Kupora (Nguva yeGel uye Nguva Yekurapa)

Nguva yeGel: Inoyera nguva kubva pakupisa kusvika pakurasikirwa nekuyerera kwemvura (mamiriro egel) patembiricha yakatarwa (semuenzaniso, 175°C) (pa GB/T 14049). Kazhinji inodiwa: masekondi 50-150 (inogadziriswa zvichienderana nekukora kwechikamu; zvikamu zvakakora zvinoda nguva yakareba zvishoma yegel kudzivirira kusapora kwemukati).

Nguva Yokupora: Inoyera nguva inodiwa kuti ipere zvachose patembiricha yakatarwa uye kumanikidzwa (zvinoenderana nekuchinja kwekuomarara kwesampuli dzebvunzo dzakaumbwa; semuenzaniso, kuomarara kweBarcol kwe80 kana kupfuura kunoratidza kupora kwakazara). Kazhinji ka3-5 nguva yegel.

Kukosha: Kupisa nekukurumidza kunogona kukonzera kushushikana mukati uye kutsemuka kwezvigadzirwa; kupisa kunonoka zvakanyanya kunorebesa nguva yekugadzira uye kunoderedza kushanda zvakanaka.

3. Chiyero chekudzikira (Kugadzikana kweDimensional Mushure meKuumbwa)

Nzira Yekuedza: Gadzira sampuli yakajairika (semuenzaniso, 120mm × 120mm × 3mm). Mushure mekutonhorera kusvika patembiricha yemumba, yera saizi chaiyo yemuenzaniso. Enzanisa izvi nehukuru hwechiumbwa kuti uverenge chiyero chekupwanya (Shrinkage Rate = (Mold Dimensions – Specimen Dimensions) / Mold Dimensions × 100%).

Maitiro Ekutonga:Phenolic molding compoundKudzikira kunowanzova pakati pe0.4% kusvika 1.2% (kuderera nezvinozadza zvisingasanganisike, kukwira zvishoma nezvinozadza zvisingasanganisike). Kudzikira kwekudzikira kwechikamu kunofanirwa kuva ≤±0.2% kudzivirira kutsauka kwehukuru muzvigadzirwa zvakapedzwa.
