Danho 1: Kugadzirira kwezvinhu zvimbichimbi - Furo rakanaka, musimboti wemidziyo ndiyo kiyi
Silicone zvinhu: Izvi zvinoshanda se "base" yefuro (inoratidzwa mune yemvura silicone fomu), inochengetedza fluidity pakamuri tembiricha kuti ibatane zvisina musono nezvimwe zvikamu. Kuchena kunoratidza kugadzikana kwefuro (-60 madhigirii kusvika 200 madhigirii ekushivirira kwetembiricha) uye elasticity. Yekutanga liquid silicone inovimbisa kukurumidza kudzoka mushure mekudzokororwa kudzokororwa, kudzivirira kushandiswa kwenguva refu kubva mukukwegura kana kuoma.
Fume silica (fume-bonded silica): Iyo "structural reinforcement agent" yefuro. Iyi poda chena yakanaka, kana yakasanganiswa nesilicone yemvura, inoshanda se "microscopic framework" inotsigira chimiro, ichiwedzera kusimba kwefuro kubvaruka uye simba--. Pasina iyo, iyo silicone ine furo yaizove yakapfava uye isina kusimba, isingakwanise kumirisana nekumanikidzana kwepasirese uye kupokana panguva yekushandiswa.
Ehe, zvichienderana nemamiriro ekushandisa, nhamba diki yezvikamu zvekubatsira (senge inopupuma mumiririri kupa simba rekuwedzera uye vulcanizing mumiriri kukurudzira kurapa) ichawedzerwa, asi liquid silicone uye fumed silica inogara iri "core CP" inosarudza kuita kwefuro.
Danho rechipiri: Sanganisa uye kurunga - Rega zvinongedzo "zviswedere"
Kana zvigadzirwa zvagadzirwa, vanopinda mune yakakosha yekusanganisa mudziyo kuti "timu kumusoro". Iyo fluidity yesilicone yemvura inoita kuti musanganiswa uwedzere kushanda, asi pane maviri akakosha mapoinzi:
Kudzora tembiricha: inofanira kuchengetedzwa pazasi 50 dhigirii, zvikasadaro furo rinozotevera "richatadza kudzora" pamberi;
Nguva yekusanganisa: kazhinji 20-maminetsi makumi matatu, kusvika gasi sesilica yaparadzirwa zvachose, uye mukomboni werabha unoratidza chimiro chakafanana uye chakapfava -- sekirimu yakanyatso kusanganiswa, isina pfungwa, kuitira kuti maburi emhepo afanana mushure mekupupa.
Chii chinoitika kana kusanganiswa kusina yunifomu? Mune dzimwe nzvimbo, gasi chikamu silica masumbu uye furo richava rakaoma; mune dzimwe nzvimbo, zviri mukati hazvina kukwana uye furo richanyanya kupfava uye nyore kupaza. Nokudaro, danho iri ndiro hwaro hwe "uniform foaming".
Nhanho 3: Kuumbwa kwefuro -- Iyo "shanduko nguva" yefuro
Iri ndiro danho rinoshamisa zvikuru! Musanganiswa wakasanganiswa unotumirwa ku "foaming workshop" uye inoshandurwa kuburikidza nekuita:
Continuous Foaming Process: Mass Production ye "Rolls/Plates" Chekutanga, pre-makomisheni erabha akagadzirwa akanyatsoiswa{1}}akatsikirirwa mumashizha makobvu akafanana pachishandiswa midziyo yakakosha. Iyi nhanho inogadza hwaro hwekuva nechokwadi chekupedzisira chigadzirwa flatness. Mashizha acho anobva atakurwa zvakanaka pamabhandi ekutakura oiswa mukamuri-refu-yakareba-yekudzivirira tembiricha---nzvimbo yepakati yekupupa furo nekuomesa. Mukati mekamuri, machira erabha paanenge achifambira mberi nebhandi rekutakura, anosangana nemhepo inoputika pasi pekupisa kwakanyanya: Zvinhu zvishoma nezvishoma zvinoumba masero akakwana, mayunifomu ane vhoriyamu yakawedzerwa, panguva imwe chete achirapwa kupisa kwekusimudzira elasticity uye kugadzikana kwechimiro.
Kana zvinhu zvacho zvichibuda muchoto, zvave mupumburu wefuro neuniform texture uye flat shape (kana kucheka mumashizha sezvinodiwa).
Key: Mapores anodzorwa sei? Unogona kushamisika: Sei mamwe mafuro efuro aine maburi sesesame (0.1-0.5mm) uye mamwe senge bhinzi (1-3mm)?
• Inonyanya kusarudzwa nehuwandu hwehuputi hwehuputi uye kupisa kwekupisa: iyo inowedzera furo, iyo inokurumidza kupisa, yakakura gomba remhepo (yakakodzera kubatwa kwekuvhunduka uye kuvhara inzwi); kana zvisina kudaro, gomba remhepo rakanaka (rakakodzera kuvhara mvura).
• Maburi efuro emhando yepamusoro anofanirwa kugovaniswa zvakaenzana -- Kana ukatariswa negirazi rinokudza, saizi yacho yakangofanana, uye hapazove nekuvhiringidzika kwe "makomba mahombe pamusoro pemakomba madiki", ndiko kuita kwemaitiro.
Danho 4: Tumira-kugadzirisa -- "ita ongororo yemuviri uye kugadzirisa zvinhu" zvefuro
Furo rangopupuma harigone kushandiswa zvakananga. Inoda kuitwa "fine grinding" : second vulcanization: Iise muovheni inenge 200℃kwe2-4 maawa kuti ubvise zvinhu zvinopisa zvasara uye kudzivirira "kuzora" kana kupera panguva yekushandiswa kunotevera. Kucheka / Kucheka: Zvigadzirwa zvemapepa zvinochekwa kuita mashizha akajairwa, uye mipendero yezvikamu zvisina kujairika yakatsikwa pasi kuti ive nechokwadi chechiyero (semuenzaniso, kune furo risina mvura, kukanganisa hakufanirwe kudarika 0.1mm, zvikasadaro inogona kudonha). Performance spot-cheki: Kuyera density (kubva pa0.3 kusvika 0.8g/cm³, yakagadziridzwa sezvinodiwa) uye compression rebound rate (kuona hupenyu hwesevhisi).
