Plastic Handles
Ua los ntawm cov yas ua cov khoom siv raw, cov yas muaj cov khoom hluavtaws siab -molecular compounds-tshwj xeeb yog *polymers* (tseem hu ua * macromolecules*). Cov tshuaj no feem ntau hu ua "plastics" lossis "resins" thiab muaj peev xwm ua tau dawb do molded rau hauv ntau yam duab thiab qauv. Yas kov yog tsim los ntawm kev txhaj tshuaj molding tshuab; pwm yog tsim raws li cov kev xav tau tshwj xeeb, tso cai rau cov leeg ua haujlwm hauv ib lub voj voog txhaj tshuaj. Lawv tuaj yeem ua ke nrog cov khoom siv zinc alloy (tsim los ntawm kev tuag-casting) los tsim cov khoom sib dhos. Cov txheej txheem saum npoo tuaj yeem suav nrog kev pleev xim, electroplating, enamel filling, thiab lwm yam kev kho mob. Ib tus neeg sawv cev hauv tsev tsim khoom tshwj xeeb hauv kev tshawb fawb thiab tsim cov yas tuav yog Cangnan Maoquan Hnab Accessories Factory. (Ceeb toom ntawm Terminology: Ib qho * txhaj tshuaj molding tshuab*-tseem hu ua * txhaj tshuaj molding xovxwm* lossis *injector*- yog cov khoom siv tseem ceeb uas siv los tsim ntau yam khoom yas los ntawm kev siv cov pwm los ua cov khoom siv thermoplastic lossis cov khoom siv thermosetting. Cov tshuab no tau muab faib ua ntsug, kab rov tav, 12 lub tshuab pwm thiab cov khoom siv hluav taws xob. siv kev kub siab rau cov yas molten, yuam nws yuav tsum tau txhaj rau hauv thiab ua tiav cov kab noj hniav ntawm pwm.)
Hardware Handles
Cov khoom siv kho vajtse ib txwm muaj-tseem hu ua "khoom me me"- xa mus rau ntau yam khoom siv hlau tsim los ntawm cov ntaub ntawv xws li hlau, hlau, lossis txhuas los ntawm kev ua lub cev xws li forging, dov, txiav, thiab cov txheej txheem zoo sib xws. Piv txwv suav nrog cov cuab yeej kho vajtse, cov khoom siv kho tshuab, txhua hnub- siv cov khoom siv kho vajtse, cov khoom siv vaj tsev, thiab cov khoom siv ruaj ntseg. Feem ntau cov khoom "khoom siv me me" tsis yog tsim los ua cov khoom siv zaum kawg. (Ceeb toom ntawm Terminology: *Hardware* [Suav: *Wujin*] Ameslikas hu ua "tsib hlau": kub, nyiaj, tooj liab, hlau, thiab tin.
Ntoo kov
* Ntoo * yog hais txog cov khoom siv tawv, fiber ntau pom hauv qab cov tawv ntoo hauv cov stems thiab ceg ntawm cov ntoo thiab cov ntoo. Hauv cov kab mob hauv cov nroj tsuag, cov tshuaj muaj pes tsawg leeg ntawm cov phab ntsa ntawm tes sib txawv heev, vim tias cov phab ntsa no feem ntau ua impregnated nrog ntau yam ntxiv. Piv txwv ntawm cov tshuaj xws li cutin, suberin, lignin, thiab mineral deposits. * Lignin * yog cov khoom siv hydrophilic uas muaj qhov nyuaj heev; Yog li ntawd, cov phab ntsa ntawm tes uas tau dhau los ua * lignification * (kev koom ua ke ntawm lignin) tsis yog tsuas yog muaj zog txhua yam, tab sis kuj khaws lub peev xwm tso cai rau kev tso dej. Rope Handles
Tsav los ntawm tib neeg nrhiav kev ua tiav hauv lub neej txhua hnub thiab kev nce qib sai ntawm kev lag luam, txoj hlua tsim tau hloov zuj zus. Dab tsi yog ib qho kev sib dhos ntawm ob peb strands tau hloov mus rau hauv cov qauv sib txawv ntawm 2, 3, 8, 16, 24, 32, lossis 48 strands. Qhov kev hloov pauv no tau ua rau cov hlua ntawm qhov chaw uas muaj qhov zoo dua thiab zoo nkauj zoo nkauj. Cov hlua no tuaj yeem siv tau siv ib qho xim lossis ib qho qauv ntawm ntau cov xim, muab qhov pom kev zoo nkauj. Cov ntaub ntawv siv yog ntau haiv neeg, xws li cov fibers ntuj -xws li hemp, xibtes fiber, paj rwb, thiab nylon- mus rau hluavtaws fibers xws li polypropylene thiab polyester, nrog rau hlau hlau; yog li ntawd, txoj hlua tes tam sim no yog qhov pom nyob rau hauv lub neej txhua hnub.
Tawv tawv
Tawv yog cov khoom siv los ntawm cov tsiaj nkaum uas tau ua tiav lub cev thiab tshuaj lom neeg ua haujlwm -tshwj xeeb yog tshem tawm cov plaub hau thiab tanning- los hloov lawv cov qauv, ua rau lawv tiv taus kev lwj. Hauv paus, tawv muaj cov protein ntau fibers nruj nreem sib txuas hauv peb-qhov loj me. Nws nto nta ib tug txawv "grain txheej" yam ntxwv ntawm tej yam ntuj tso textures thiab ib tug maj mam luster, muab ib tug tactile kev paub uas yog ob qho tib si xis thiab qab ntxiag mus kov.
Alloy tuav
Feem ntau ua piv txwv los ntawm zinc alloy handles, ib qho alloy kov yog cov khoom uas muaj cov khoom siv hlau uas yog tsim los ntawm ob los yog ntau dua cov khoom sib xyaws -uas yuav yog hlau lossis tsis yog - hlau- los ntawm cov txheej txheem tshwj xeeb. Feem ntau, alloys yog tsim los ntawm melting cov ntsiab lus nyob rau hauv ib homogeneous kua sib tov thiab cia nws mus solidify. Raws li tus naj npawb ntawm cov ntsiab lus, cov alloys tuaj yeem muab faib ua binary alloys (ob lub ntsiab lus), ternary alloys (peb lub ntsiab lus), thiab ntau yam - cov khoom sib txuas (ntau yam). Tuam Tshoj sawv ua ib lub teb chaws ntxov tshaj plaws hauv ntiaj teb los tshawb fawb thiab tsim cov alloys; Thaum lub sij hawm Shang Dynasty (tshaj li 3,000 xyoo dhau los), kev ua haujlwm ntawm tooj liab (tooj liab-} tin alloy) twb tau siab heev. Tsis tas li ntawd, nyob ib ncig ntawm lub xyoo pua 6 BCE (thaum lub caij nplooj ntoos hlav lig thiab lub caij nplooj zeeg), cov neeg txawj ntse twb forging{12}}thiab txawm tias tshav kub- kho- rab ntaj ntse ua los ntawm cov hlau.
