Hauv kev txhav thiab tinning, rosin feem ntau yog siv los ua flux. Khoom rosin yog pob tshab prickly loj nrog qhov xim ntawm txhua qhov ntxoov ntawm Amber. Rau qhov yooj yim ntawm kev ua haujlwm, kev daws teeb meem ntawm rosin hauv cawv los yog acetone feem ntau siv, uas qee zaum hu ua kua rosin.
Cawv tov cawv ntawm rosin
Lub luag haujlwm tseem ceeb ntawm rosin thaum zawm yog los tiv thaiv cov hlau qhov chaw los ntawm oxidation. Ib qho kev daws teeb meem ntawm rosin hauv cov dej cawv ethyl kis tau zoo dua li ntawm cov hlau dua molten rosin, uas ua rau txhawm rau kev lag luam ntau thiab lub foob nws tus kheej huv. Rosin nyob rau hauv daim ntawv ntawm txoj kev daws teeb meem tau thov rau cov hlau ntshiab huv ua ntej cov ntsiab lus soldering sov, uas nyob rau hauv lem ntxiv tiv thaiv qhov oxidation ntawm cov chaw no. Ib qho kev daws teeb meem ntawm rosin hauv cov dej cawv ethyl yog qhov tsawg tshaj plaws tshuaj lom hauv kev sib piv nrog cov tshuaj hauv acetone, yog li nws pom cov ntawv thov loj tshaj hauv thev naus laus zis.
Tau txais rosin
Koj tuaj yeem tau rosin koj tus kheej yog tias xav tau. Spruce lossis ntoo thuv ntoo tawv yog qhov haum li cov khoom siv raw. Siv ib lub khob qub khob thiab qhwv sab hauv ntawm nws nrog ntawv ci txhuas. Cais, hauv cov hlau tuaj yeem los ntawm hauv cov kaus poom zaub mov, yaj rau cov roj, ua kom nws npau. Muab cov khib nyiab uas tau ntab rau saum npoo nrog rab diav hlau. Thaum lub rwj dhau lawm, sai sai hliv cov kua rau hauv ntawv ci-qhwv lub khob. Tos rau rosin kom txias, co nws tawm hauv lub khob thiab tev tawm ntawm ntawv ci. Tus txheej txheem no ua nplaim taws; cov haujlwm no yuav tsum tau nqa tawm hauv cov cua qhib. Thaum lub sij hawm qhuav distillation ntawm cob, turpentine raug tso tawm, lub vapors ntawm uas muaj tshuaj lom, lawv tsis tuaj yeem nqus tau. Rau tib qho laj thawj, tsis tuaj yeem siv cov khoom siv rau soldering.
Kev nrhiav kua rosin
Kua rosin tuaj yeem muas tau. Piv txwv li, nws raug muag raws li cov lag luam muaj npe LTI-120. Tab sis koj tuaj yeem ua rau koj tus kheej. Siv lub khob iav me me nrog kaw ntom ntom. Sau nws nrog ib feem peb ntawm cov tsoo rosin thiab sau nws nrog ethyl cawv. Koj tuaj yeem noj ob qho tib si kev kho mob thiab dej cawv, tab sis nws yog qhov yuav tsum tau siv 96%. Kaw lub khob ntim nruj nreem nrog cov nres. Kev npaj ua kua rosin rau soldering tsis tas yuav tsum muaj qhov tshwj xeeb tshwj xeeb, thiab txhua txoj haujlwm tuaj yeem nqa tawm "los ntawm qhov muag". Nrog rau kev ntxhov siab nyob rau hauv chav tsev kub, txheej txheem kev cais tawm yuav siv sijhawm 2-3 hnub. Cov av hauv nkoj tsis tau tso tseg yuav nyob hauv qab ntawm lub nkoj - qhov no yog cov khib nyiab. Ncuav cov tshuaj rau hauv lub vial huv yam tsis muaj kev cuam tshuam nrog nag lossis daus. Nws yog qhov zoo tshaj plaws rau ncuav kua rosin rau hauv vials nrog txhuam ntawm qhov nres, xws li txhuam yog yooj yim rau kev thov flux rau saum npoo.
Cawv cov kua roj vanish
Rosin yog zaub pos hniav. Kev daws cov zaub mov hauv cov cawv tso rau hauv cawv yog hu ua cawv varnishes. Cov kua rosin ua cov kua roj vanish yog siv los npog cov khoom ntoo, uas ua rau lawv noo-pov thawj thiab tsis-qhov. Cov txheej txheej tsis muaj zog ntawm rosin yog acid-resistant, uas ua rau nws siv tau cov rosin varnishes thaum etching luam tawm cov laug cam Circuit Court, yooj yim rau lawv cov soldering ntxiv. Qhov tsis zoo ntawm dej cawv rosin kua roj vanish yog qee qhov seem nplaum ntawm qhov chaw tom qab nws dries, tshwj xeeb tshaj yog thaum ceeb toom. Tab sis qee tus kws tshaj lij paub yuav ua li cas tig qhov kev tsis zoo no mus rau qhov ua kom zoo dua, yog li tsim cov ntawv sau lo tiv thaiv.
