Ijeli ye-silica isetshenziswa kakhulu emakethe ngoba ayikhiphi izinto ezinobuthi, inokuthinta okuthambile nokunethezekayo, futhi inezakhiwo ezinhle zomzimba namakhemikhali emazingeni okushisa aphezulu kanye namazinga okushisa aphansi (-60c~+300c). Kukhona amanye ama-polymer ambalwa angakwazi ukuwafanisa.
I-elastomer eqinile, engcono kunokuvalwa kwerabha, ukufakwa ugesi okuhle kakhulu, nokumelana namakhemikhali, izinto zokubasa, uwoyela, namanzi, into enhle yokubhekana nezimo ezingezinhle.
Embonini, njengezigxivizo zikawoyela, okhiye bekhibhodi, izinto zokufaka ugesi kagesi, izingxenye zemoto, izidingo zansuku zonke njengama-pacifiers, ama-catheter okwenziwa, ama-respirators, izibuko zamaxoxo, izicathulo zesikhumba namateki, iziqukathi zokudla, njll.
Uma unesidingo se-sliicone sokukhiqiza, vele uxhumane nathi ukuze uthole ulwazi olwengeziwe.
Uyini umehluko phakathi kwejeli ye-silica ewuketshezi kanye nejeli ye-silica eqinile?
I-silicone ewuketshezi
Ijeli ye-silica ewuketshezi iwuhlobo lwerabha ye-silicone eqinile enezinga eliphezulu lokushisa. Kuwujeli oluwuketshezi olunoketshezi oluhle, ukuvuthwa okusheshayo, ukuvikela okuphephile nokuvikeleka kwemvelo, futhi kungahlangabezana ngokuphelele nezidingo zebanga lokudla.
Ijeli ye-silica eqinile
Ijeli ye-silica eqinile iwuhlobo lwe-saturated polymer elastic material, enezici zokumelana nezinga lokushisa eliphezulu, ukumelana nokubanda, ukumelana ne-solvent, ukumelana nokunamathela, i-anti-stick, ukwahlukanisa ugesi, ukumelana namakhemikhali futhi inobubanzi bezicelo.
1. Ijeli ye-silica ewuketshezi nokubukeka okuqinile
(1) Njengoba igama lisho, ijeli ye-silica ewuketshezi iwuketshezi futhi inoketshezi
(2) Ijeli yesilika eqinile iqinile, ayinamali!
2. Ukusetshenziswa kwejeli ye-silica ewuketshezi kanye nejeli ye-silica eqinile
(1) Ijeli ye-silica ewuketshezi ngokuvamile isetshenziswa emikhiqizweni yezingane, emikhiqizweni yasekhishini, nasezimpahleni zokwelapha, ezingathinta ukudla kanye nomzimba womuntu ngokuqondile.
(2) Ijeli ye-silica eqinile ngokuvamile isetshenziswa ezidingweni zansuku zonke nasezingxenyeni ezixubile zezimboni nezingxenye zezimoto, njll., ububanzi bokusebenza bubanzi uma kuqhathaniswa.
3. Ukuphepha kwejeli ye-silica eqinile kanye nejeli ye-silica ewuketshezi
(1) Ijeli ye-silica ye-Liquid iyinto esobala ephezulu futhi ephezulu yokuphepha kwebanga lokudla, ukubumba ngaphandle kokwengeza i-ejenti ye-vulcanizing nezinye izinto ezisizayo, ukubunjwa kokuphakelayo okuvalwe uphawu.
(2) Ijeli ye-silica eqinile iyinto esobala yokuvikela imvelo, ukwakha idinga ukwengeza into elaphayo ukuze kusheshiswe isikhathi sokwakha, kanye nokuvula ukubumba kokubunjwa kwesikhunta.
4. Ijeli ye-silica ewuketshezi kanye nendlela yokubumba ijeli ye-silica eqinile
(1) I-silicone ewuketshezi iwukubumba umjovo werabha ye-silicone ewuketshezi (LSR): igama eligcwele lomjovo lokubumba irabha ye-silicone ewuketshezi, imishini yokuphulukisa yomshini wokubumba umjovo.
Umshini wokubumba umjovo unenqubo yezobuchwepheshe elula kakhulu, akudingeki kube inqubo yezithako zeglue ezisezingeni eliphezulu, ukuxuba, ukuvala, izinto ezibonakalayo kanye nenqubo, oyedwa kuphela wabasebenzi othatha imikhiqizo), imikhiqizo enembile kakhulu (ukubumba umjovo ngaphambi kwayo yonke into. Uhlelo lwemanuwali luthathelwe indawo umshini A), ukuphuma okuphezulu (ukuxuba iglue ye-A/B, ngaphansi kwezinga lokushisa elithile imizuzwana embalwa ukuze lilolonge), londoloza, londoloza ugesi, londoloza impahla nokunye okuningi kokufaneleka, kungakhiqiza yonke ingcina yokushisa ephezulu. imikhiqizo yokukhiqiza! Iwukuthuthukiswa kwezinto zenjoloba ye-silicone evamile eminyakeni embalwa ezayo.
(2) Ukubumba okuqinile kwejeli ye-silica kuyizinto ezingavuthiwe eziwucezu oluqinile, ngomshini wokuhlanganisa umshini wokusika, umshini wokusika unqunywa ube yimikhiqizo kanye nokubunjwa komjovo ubukhulu obufanele nobukhulu, bese kuba isikhunta, umshini wokubumba ukucindezela ngaphansi. ukushisa okuthile ekubumbeni. Demoulding kanye nemikhiqizo plastic mayelana efanayo, futhi kudingeka ukuhlanza isikhunta.
5. Ijeli ye-silica ewuketshezi kanye nemikhiqizo yejeli ye-silica eqinile indlela yokuhlukanisa
Ukubonakala kwejeli ye-silica ewuketshezi kuphezulu, akunaphunga, futhi umkhiqizo unomlomo womjovo weglue. Ijeli eliqinile elicwebezelayo elicwebezelayo eliphansi, i-ejenti elimazayo noma enye iphunga elimnandi lekhava, umkhiqizo ongenawo umlomo womjovo
