Kev tsom xam ntawm iav raj yam ntxwv thiab hom

I. Txheej txheem cej luam ntawm cov txheej txheem iav raj mis

Kev tsim lub raj mis iav pib nrog pwm tsim thiab tsim khoom. Cov khoom siv tseem ceeb yog quartz xuab zeb, sib xyaw nrog lwm cov ntaub ntawv pabcuam, yaj rau hauv cov kua hauv lub xeev ntawm qhov kub thiab txias, tom qab ntawd nchuav rau hauv pwm. Tom qab txias, txiav, thiab tempering, lub khob iav zaum kawg yog tsim. Cov iav fwj feem ntau dais cov cim nruj, uas yog ncaj qha tsim los ntawm cov pwm zoo.

Raws li kev tsim khoom, lub raj mis tsim tuaj yeem muab faib ua peb hom: tes- tshuab, tshuab- tshuab, thiab extrusion molding. Raws li muaj pes tsawg leeg, feem ntau muaj peb pawg: dej qab zib iav, lead iav, thiab borosilicate iav.

II. Cov ntaub ntawv tseem ceeb thiab cov yam ntxwv ntawm cov iav fwj

Cov ntaub ntawv tseem ceeb rau lub raj mis muaj xws li cov ntxhia hauv ntuj, quartz, caustic soda, thiab limestone. Cov iav fwj muaj qhov pom tseeb thiab tiv thaiv corrosion, thiab lawv cov khoom siv tsis hloov thaum sib cuag nrog cov tshuaj feem ntau. Lawv cov txheej txheem tsim khoom yog qhov yooj yim, pub dawb thiab ntau yam duab. Lawv muaj hardness siab, zoo tshav kub tsis kam, huv si thiab yooj yim - mus rau - huv si, thiab yog reusable.

Cov iav fwj tau dav siv los ua cov khoom ntim hauv cov khoom noj, roj, cawv, dej haus, khoom noj khoom haus, tshuaj pleev ib ce, thiab kua tshuaj industries. Txawm li cas los xij, lawv kuj muaj qhov tsis zoo, xws li qhov hnyav hnyav, kev thauj mus los siab thiab cov nqi khaws cia, thiab kev cuam tshuam tsis zoo.

III. Cov yam ntxwv thiab kev faib tawm ntawm iav fwj

Cov iav fwj yog cov ntim ntim loj hauv cov khoom noj, tshuaj, thiab tshuaj lom neeg kev lag luam. Lawv qhov zoo muaj xws li: tshuaj lom neeg ruaj khov; yooj yim sealing thiab zoo heev airtightness; pob tshab tso cai rau kev soj ntsuam ntawm cov ntsiab lus; ruaj khov kev ua tau zoo; du nto kom yooj yim kom tsis muaj menyuam; tsim kom zoo nkauj thiab nplua nuj zoo nkauj cuam tshuam; muaj zog txhua yam muaj zog los tiv thaiv lub zog sab hauv thiab sab nraud thaum thauj; thiab dav muaj thiab cov khoom siv pheej yig.

Qhov tsis zoo tseem ceeb yog lawv qhov hnyav hnyav (siab hnyav- rau- qhov muaj peev xwm piv), brittleness, thiab fragility. Txawm li cas los xij, nrog rau kev siv cov txheej txheem nyias nyias -walled lightweight technology thiab cov txheej txheem physicochemical tempering tshiab, cov kev tsis zoo no tau ua kom zoo dua qub. Yog li ntawd, txawm tias muaj kev sib tw hnyav nrog cov khoom ntim xws li plastics, tin poom, thiab cov kaus poom hlau, iav fwj ntau lawm tseem loj hlob txhua xyoo.

IV. Ntau hom iav fwj

Cov iav fwj tuaj nyob rau hauv ntau hom. Muab faib los ntawm lub peev xwm, lawv muaj xws li los ntawm cov fwj me me ntawm 1 ml mus rau lub hwj loj tshaj kaum litres; los ntawm cov duab, lawv muaj xws li puag ncig, square, irregularly zoo li tus, thiab tuav fwj; los ntawm cov xim, lawv txawv ntawm cov xim tsis muaj xim thiab pob tshab mus rau lub teeb- thaiv cov fwj hauv amber, ntsuab, xiav, thiab dub, nrog rau cov opaque milky iav fwj.

Nyob rau hauv cov nqe lus ntawm kev tsim khoom, iav fwj feem ntau yog muab faib ua ob pawg: lub raj mis molded (ua siv pwm) thiab lub raj mis tubular (tsim siv cov iav raj). Moulded fwj tuaj yeem muab faib ua qhov dav - lub qhov ncauj fwj (lub qhov ncauj txoj kab uas hla ntawm 30 mm lossis ntau dua) thiab nqaim - lub qhov ncauj fwj. Lub qub yog tsim los tuav cov hmoov, pob, thiab pastes, thaum lub tom kawg yog siv los tuav cov kua.

Raws li hom lub raj mis caj dab, lawv tuaj yeem muab faib ua cork- lub raj mis tso tseg, lub raj mis threaded, yas- lub raj mis capped, dov- lub raj mis, thiab frosted fwj. Raws li tus naj npawb ntawm kev siv, lawv tau muab faib ua ib zaug - siv "cov fwj uas siv tau" thiab rov siv tau "cov fwj siv dua." Raws li cov ntsiab lus, lawv suav nrog ntau hom xws li lub raj mis cawv, lub raj mis dej haus, lub raj mis roj, lub raj mis, lub raj mis acid, lub raj mis tshuaj, lub raj mis reagent, infusion fwj, thiab lub raj mis kom zoo nkauj.
