Boemo bo thata le bo mahlale ba mekhoa ea tlhahiso ea bona bo ama boleng ba sehlahisoa ka kotloloho, botsitso ba ts'ebetso, le ho nepahala ha ts'ebeliso. Ho tloha ho khetho ea thepa e tala ho ea ho sephutheloana sa sehlahisoa se felileng, mohato o mong le o mong o hloka taolo e tiileng ea litekanyetso tsa tekheniki le maemo a tikoloho ho netefatsa hore sehlahisoa sa ho qetela se fihlela litlhoko tsa lits'ebetso tse fapaneng. Sengoliloeng sena se hlalosa ka mokhoa o hlophisehileng ts'ebetso ea mantlha ea tlhahiso ea likhomaretsi tsa khoebo, se koahelang lintlha tsa bohlokoa tsa tekheniki le taolo ea boleng ba mehato ea bohlokoa.
1. Raw Material Pretreatment and Formulation Design
Ts'ebetso ea likhomaretsi tsa khoebo e ipapisitse le khetho ea lisebelisoa tse tala le moralo o nepahetseng oa libopeho tsa tsona. Lisebelisoa tse tala li atisa ho aroloa e le lisebelisoa tsa motheo (tse kang li-resin tsa maiketsetso le li-polymers tsa tlhaho), li-folic agents (joalo ka li-isocyanate le metsoako ea amine), li-filler (tse kang calcium carbonate le silica powder), le li-additives (tse kang li-thickeners le antioxidants). Pele ho tlhahiso, lisebelisoa tse tala li tlameha ho etsoa tlhahlobo ea bohloeki, tlhahlobo ea boholo ba likaroloana, le netefatso ea ho lumellana ho tlosa litšila kapa likarolo tse senyehileng.
Moralo oa moralo ke qalo ea ts'ebetso. Matšoao a mantlha a ts'ebetso-joalo ka ho hanyetsa mocheso (-40 degrees ho isa ho 200℃), matla a bond (matla a ho kuta A maholo ho feta kapa a lekana le 5 MPa), nako ea ho folisa (5-metsotso e 30 mochesong oa kamore), le litlhoko tsa tikoloho (VOC content Ka tlase kapa ho lekana 50 g/L) -e tlameha ho khethoa ho ipapisitsoe le moaho o le mong, ts'ebeliso ea moaho o le mong. sebopeho bonding, le ambalaji thepa lamination). Sehlopha sa R&D se sebelisa lintlha tsa liteko ho etsisa thepa ea rheological, ho folisa kinetics ea karabelo, le khanyetso ea nako e telele ea maemo a leholimo a likarolelano tse fapaneng tsa thepa e tala, qetellong e nts'etsapele sebopeho se tloaelehileng.
2. Ho Kopanya le Phatlalatso: Taolo e Bohlokoa bakeng sa ho Tšoanang
Ka mor'a hore lisebelisoa li kenngoe setsing sa motlakase ho ea ka tekanyo e hlophisitsoeng, ts'ebetso ea mantlha-ho kopanya le ho hasana-ea latela. Mokhahlelo ona o hloka{3}}motsoako o phahameng oa lebelo (1000-3000 rpm) kapa planetary mixer ho etsa bonnete ba hore motheo, pheko, li-filler le li-additive li kopantsoe hantle. Bakeng sa likhomaretsi tse nang le{11}}lihlahisoa tse phahameng (mohlala, tšepe phofo) kapa likaroloana tse kopantsoeng habonolo (mohlala, nano-silica), motsoako oa triaxial differential mixing kapa mekhoa ea ultrasonic dispersion e ea hlokoa ho qoba mathata a ts'ebetso a bakoang ke mefuta e fapaneng ea mahloriso (mohlala, ho kopanngoa ha li-interfaces).
Nakong ea ts'ebetso ea ho kopanya, liphetoho tsa mocheso li tlameha ho behoa leihlo ka nako ea sebele (hangata e bolokiloe pakeng tsa 25-60 degrees ) ho thibela mocheso o feteletseng oa sebakeng seo o ka tsosang maikutlo pele ho nako (joaloka "polymerization ea li-epoxy resins) kapa tahlehelo e feteletseng ea li-volatiles (joalo ka ho fokotseha ha motsoako o sebetsang{4}). Likhomaretsi tse ling tse khethehileng (tse kang li-acrylates tse folisang khanya) le tsona li hloka ho tsoakoa tlas'a sepakapaka sa inert (nitrogen) ho thibela oksijene ho thibela polymerization ea mahala.
3. Boitšoaro le Pheko: Mehato ea Konokono ea ho Theha Ts'ebetso
Sekhomaretsi se kopantsoeng ka mokhoa o ts'oanang se kena ka har'a mochini oa ho kopanya lik'hemik'hale kapa phetoho ea boemo ba 'mele. Bakeng sa li-adhesives tsa thermosetting (joalo ka li-phenolic resin le polyurethanes), ho futhumatsa (80-150 degree) ho etsa hore ho be le condensation kapa ho eketsa maikutlo pakeng tsa liketane tsa limolek'hule ho etsa sebopeho sa marang-rang a mararo. Bakeng sa likhomaretsi tsa thermoplastic (joalo ka polyvinyl acetal), botsitso ba morphological bo fihlelleha ka mouoane oa solvent kapa ho pholile le ho folisa.
Nako ea ho itšoara le mocheso li tlameha ho lumellana ka thata le litlhoko tsa tlhahiso. Mohlala, karabelo e folisang ea likhomaretsi tsa epoxy resin hangata e hloka ho boloka mocheso oa likhato tse 120 bakeng sa metsotso e 30 ho netefatsa hore sekhahla sa li-crosslink se kopana le maemo a boletsoeng. Kamore-mocheso{{5}ho folisa li-adhesives tsa acrylic, ka lehlakoreng le leng, ho hloka ho sebetsa butle ka likhato tse 25 bonyane lihora tse 24 ho sebelisoa catalyst (joalo ka motsoako oa organotin). Karolo ea botsofali (e emeng matsatsi a 1-3 ka mor'a karabelo) e tsoela pele ho ntlafatsa tlhophiso ea ketane ea limolek'hule, ho ntlafatsa ho feto-fetoha ha maemo le khanyetso ea sekhahla sa sekhomaretsi.
4. Phahamiso-Ts'ebetso le Tlhahlobo ea Boleng
Ka mor'a ho tsofala le ho tsofala, sekhomaretsi se sebetsa-mehato ea ho sebetsa joalo ka ho sefa (ho nepahala Ka tlase ho kapa ho lekana le 5μm) le ho ntša metsi (vacuuming ka -0.09MPa metsotso e 30) ho tlosa likaroloana tse sa sebetsanoang (tse ka bakang khatello ea maikutlo le ho fokotsa matla a sekhomaretsi). Likhomaretsi tsa mokelikeli (joalo ka li-silicone sealants) li fetisetsoa mochining oa ho tlatsa o ikatisang bakeng sa ho paka ka bongata (300ml tubes/20kg drums). Likhomaretsi tse tiileng (tse kang lithupa tsa sekhomaretsi tse qhibilihang ka mocheso o chesang) li entsoe ka extruder, e pholileng le ho seha.
Lihlahisoa tse felileng li tlameha ho etsa tlhahlobo e felletseng ea boleng, ho kenyelletsa:
• Thepa ea 'Mele: Matla a Bond (Teko ea Tensile / Shear), Thata (Lebōpo la A), Boima ba (GB/T 4472 Standard);
• Botsitso ba Lik'hemik'hale: Ho hanyetsa Metsi (80℃Boiled ka Metsing bakeng sa Lihora tsa 24), Solvent Resistance (Ethanol Immersion for 7 Days), Resistance ea Botsofali (Matla a Ts'ebetso e kholo ho feta kapa e lekanang le 80% ka mor'a Lihora tsa 500 tsa UV Irradiation);
•Tshireletso: Boima ba Metal Content (Moeta-pele ka Tlase kapa o lekana le 90 ppm), Formaldehyde ea Mahala (Ka tlase ho kapa ho lekana le 0.1 g/kg), Phallo ea VOC (E Lumellana le GB 33372-2020 Limits).
5. Packaging le Storage Management
Likhomaretsi tse fetisang tlhahlobo li tlameha ho ngoloa ka beche ea tlhahiso, bophelo ba sethala (hangata likhoeli tse 6-24), maemo a polokelo (mohlala, a sirelelitsoe khanyeng, sebakeng se phodileng, se lefifi, mocheso o ka tlase ho kapa o lekana le likhato tse 30), le lintlha tse sebetsang. Lisebelisoa tsa ho paka li tlameha ho kenella ka lik'hemik'hale (mohlala, meqomo ea polasetiki ea HDPE, mekotla ea foil ea aluminium) ho thibela ho ts'oaroa ha sekhomaretsi. Libaka tsa polokelo li tlameha ho laola mongobo (ka tlase kapa ho lekana le 60% RH) le ho fetoha ha mocheso (± 5 degrees). Litlhahlobo tsa khafetsa tsa libaka li etsoa lethathamong ho netefatsa hore lihlahisoa tse fuoang bareki li lula li fihlela litlhoko tsa moralo oa pele.
Qetello
Ts'ebetso ea tlhahiso ea likhomaretsi tsa khoebo ke phello ea ts'ebelisano-mmoho ho pholletsa le lithuto tse ngata (polymer chemistry, engineering engineering, le taolo ea boleng). Mohato o mong le o mong ho tloha ho thepa e sa sebelisoang ho ea ho sehlahisoa se felileng e tlameha ho tsamaisoa-ho tsamaellana le data, e fihlelle ho leka-lekana lipakeng tsa tšebetso le litšenyehelo ka taolo e hlokolosi. Ha litlhoko tsa indasteri tsa theknoloji ea bonding li ntse li eketseha (tse kang-matla a matla bakeng sa limojule tse ncha tsa betri ea matla le micron{4}}bonding e nepahetseng ea boemo ba semiconductor packaging), mekhoa ea tlhahiso ea sekhomaretsi e tla tsoela pele ho fetoha ho ea ho e tala (tlase{5}}VOC), e sebetsang haholoanyane (motlakase o kopantsoeng oa motlakase le mocheso oa mocheso){6} Leha ho le joalo, lits'ebetso tsa mantlha tse tsitsitseng e ntse e le motheo oa mantlha bakeng sa boqapi.
