Kev tshuaj xyuas cov ntawv sau, Kuv ntseeg tias koj yuav ntsib ntau zaus. Kuv ntseeg tias ntau tus neeg koom tes tau tshuaj xyuas gel cwjmem, cwj mem ballpoint, refills, staplers thiab lwm yam ntawv sau. Hnub no, kuv xav qhia rau koj txog kev soj ntsuam yooj yim.
Gel cwj mem, ballpoint cwj mem thiab refills
A. Cov nibs ntawm gel cwj mem tau muab faib ua tsib hom: ultra-nplua, ntxiv-nplua, nyias, nruab nrab thiab tuab, raws li qhia hauv cov lus hauv qab no:
B. Muaj plaub hom kev refills uas muab cov duab thiab cov ntaub ntawv loj: J, K, L, thiab G2 (saib daim duab 1 txog 2 thiab Tables 2 thiab 3), uas txawv ntawm J, K, L, thiab G2 raws li N. hom.
C.Sau tester teem caij:
(1) Sau lub kaum sab xis: 50-70 °, xaiv lub kaum sab xis sau ntawv nrog cov hlua khi feem ntau;
(2) Sau ceev: (4.5 ± 0.5) m / min, uas yog (7.5 ± 0.8) cm / s;
(3) Sau hom: txuas txuas txuas txuas nrog qhov sib nrug ntawm 2mm txog 5mm (circumference ntev 10cm)
D. Kev xeem yuav tsum:
(1) Yuav sau tau yooj yim hauv 10cm. Kev sau ntawv ntev ntawm qhov sib txawv ntawm cov nibs tau qhia nyob rau hauv Table 4. Yuav tsum tsis muaj cov kab tawg yooj yim thiab kev hloov ceev ntawm qhov pib thiab qhov kawg ntawm cov stitches.
(2) Permeability: Cov qauv ntawv muab tso rau hauv qhov chaw sim rau 24 teev, thiab tsis muaj qhov pom tseeb nyob rau sab nraum qab ntawm daim ntawv los ntawm kev tshuaj xyuas qhov muag.
(3) Dryness: Kos ib txoj kab ncaj nraim ntawm daim ntawv xeem raws li cov lus sau saum toj no, lub kaum sab xis, thiab nrawm. Tom qab 20 vib nas this, so cov kab ncaj nraim nrog lub lwv vertically. Cov stitches yuav tsum tsis muaj stains.
(4) Reproducibility: Luam cov qauv ntawv nrog lub tshuab luam ntawv, thiab cov kab luam ntawv tseem pom.
(5) Dej tsis kam: Tom qab cov qauv ntawv muab tso rau hauv qhov chaw sim rau 2 teev, nws yog immersed nyob rau hauv distilled los yog deionized dej rau 1 teev, thiab cov stitches tseem pom tom qab ziab. Cov khoom no yog xaiv tau thiab siv rau cov cwj mem gel thiab cov khoom siv ntxiv uas cim "Water Resistant" (WR).
(6) Lub teeb nrawm: nthuav tawm cov qauv ntawv thiab cov qauv ntaub plaub xiav xiav (ib nrab npog) nyob rau hauv lub fading meter lossis xenon teeb kom txog rau thaum cov xim sib txawv ntawm qhov raug thiab tsis pom 3 xiav wool standard qauv mus txog qib 4 ntawm cov qauv grey daim npav, kab kab kab tseem pom.
(7) Kev sau ntawv tsis sib xws: Tom qab tus cwj mem tsis siv (tsis muaj lub hau cwj mem) tawm ntawm cov dej ib txwm, tom qab muab tso rau hauv kab rov tav rau 24 teev nyob rau hauv qhov kev xeem ib puag ncig, kos ib txoj kab ncaj nraim nrog tes, thiab sau ib txoj kab txuas ntxiv rau hauv 10 cm.
(8) Preservability: nyuam qhuav tsim, tsis siv cov cwj mem (nrog lub kaus mom) yog muab tso rau kab rov tav ntawm qhov kub ntawm (40 ± 2) ° C thiab cov av noo ntawm (55 ± 5)% rau 90 hnub, thiab lawv raug sim rau kev sau ntawv ua tau zoo thiab ua tau raws li qhov yuav tsum tau ua.
Cov ntsiab lus:
1. Rau plug-in nruab nrab thiab ballpoint cwjmem, qhov haum nruab nrab ntawm lub hau thiab lub thoob yuav tsum tau nyob nruab nrab. Feem ntau, tuav tus cwj mem nrog ib txhais tes, thawb lub hau nrog koj tus ntiv tes xoo, thiab thawb nws tawm. Txwv tsis pub, nws yog suav hais tias yog ib tug nruj haum.
2. Rau cov cwj mem nrog lub hnab ntim rov qab rau ntawm tus cwj mem, nws yuav tsum tau muab lub foob rov qab tsis tuaj yeem rub tawm tau yooj yim los tiv thaiv menyuam yaus los ntawm kev nqos los ntawm kev yuam kev. BS7272-test yog xav tau, thiab txoj kev xeem yog raws li nram no:
a. Pen Cap Safety Requirements:
① Cov kev xav tau rau qhov loj ntawm lub hau cwj mem: lub hau cwj mem tsis tuaj yeem dhau los ntawm lub nplhaib tshwj xeeb lossis lub hau cwj mem tsis tuaj yeem hla lub nplhaib ntsuas qhov tsawg kawg yog 5 hli. Txoj kab uas hla ntawm lub nplhaib ntsuas yog 16 hli thiab lub thickness yog tsawg kawg yog 19 hli;
② Cov kev xav tau rau qhov chaw cua ntawm lub hau cwj mem: tsawg kawg yog 6.8m ㎡, yog tias nws yog ib lub qhov, nws yuav tsum tau 3.4 m ㎡;
③ Cwj mem cap qhov cua qhov yuav tsum tau: tsawg kawg yog 8L / Min ntawm 1.33KPa.
b. Cov kev xav tau rau sab nraum qab ntawm tus cwj mem:
① Cov kev xav tau ntawm qhov loj ntawm lub nraub qaum: lub nraub qaum tsis tuaj yeem dhau los ntawm lub nplhaib tshwj xeeb ntsuas, txoj kab uas hla ntawm lub nplhaib ntsuas yog 16 hli, thiab lub thickness yog tsawg kawg yog 19 hli;
② Lub ntsaws rov qab protrudes los ntawm qhov kawg ntawm tus cwj mem, thiab lub nraub qaum ntsaws yuav tsum tiv taus qhov tsawg kawg nkaus ntawm 50N;
③ Lub nraub qaum rov qab ua tiav rau hauv qhov kawg ntawm tus cwj mem thiab yuav tsum tiv taus qhov tsawg kawg nkaus ntawm 10N;
④ Cov kev xav tau rau qhov tsawg kawg nkaus ntawm qhov kawg ntawm lub qhov ntsaws rov qab: qhov ntev ntawm qhov uas tuaj yeem tuav tau yuav tsum tsis pub tshaj 1MM, thiab qhov ntev tag nrho yuav tsum tsis pub tshaj 3MM;
⑤ Qhov yuav tsum tau ua rau lub qhov cua ntws tawm ntawm lub ntsaws nraub qaum: ntawm 1.33KPa, tsawg kawg yog 8L / Min tau ntsib, thiab lub ntsaws nraub qaum yuav tsum tiv taus qhov tsawg kawg nkaus ntawm 10N.
3. Rau cov cwj mem nrog clips, yuav tsum tau ua qhov kev ntsuam xyuas elasticity. Nws yuav tsum muaj peev xwm tuav tau peb daim ntawm 80g A4 ntawv. Nyob rau tib lub sijhawm, clip yuav tsum muaj elasticity zoo. Feem ntau, nws yog qhov zoo rau flick nws nrog koj cov ntiv tes 3-5 zaug yam tsis tau tawg.
4. Yog hais tias tus cwj mem tseem muaj xim luam ntawv qauv, ua 3M daim nplaum nplaum (kos 3M daim kab xev rau tus qauv yam tsawg kawg 1 feeb, tom qab ntawd rhuav tshem daim kab xev ntawm 45 °, thiab qhov tev ntawm cov lo lo ntxhuav. screen tsawg dua 5%.
stapler
A. Stapler specifications yuav muab faib ua plaub pawg:
8 gauge stapler, 10 gauge stapler, 12 gauge stapler thiab tuab ply stapler.
B. Kev pabcuam lub neej ntawm stapler feem ntau yog 20,000 zaug.
C. Muaj nuj nqi thiab kev xav tau:
1. Cov khoom seem yuav tsum sib koom ua ke yooj yim. Thaum nailing, tus ntsia thawv pusher yuav tsum txav mus rau hauv txoj kev ntsia hlau thiab tuaj yeem rov pib dua lub sijhawm. Cov ntawv xovxwm staple tuaj yeem thawb lub stapler tawm ib qho los ntawm ib qho thiab khoov rau hauv cov ntsia hlau zawj, thiab tuaj yeem ua tiav tag nrho cov staples hauv txoj kev ntsia hlau.
2. Sab nrauv ntawm cov xim zaj duab xis ntawm lub stapler yuav tsum tiaj tus, nrog rau cov xim tib yam, tsis muaj particle impurities, tsis pom tseeb pinhole npuas, xim tev thiab lwm yam tshwm sim.
3. Qhov saum npoo ntawm stapler txheej yuav tsum tsis txhob blackened, pinholes, yellowing thiab lwm yam tsis xws luag, thiab yuav tsum tsis muaj oxidation loj yog tias nws tsis yog lub ntsiab.
4. Lub stapler ntsia thawv phaj thiab qis ntsia hlau zawj yuav tsum tau kuaj xyuas qhov hardness.
Cov ntsiab lus ntawm lwm cov ntawv sau:
1. Watercolor cwj mem thiab cov cim:
① Siv 2KG quab yuam rau lub nib los saib seb lub nib puas yog indented.
② rub tus cwj mem nrog 1KG quab yuam, thiab saib seb lub hauv paus ntawm tus cwj mem raug rub tawm li ntawm 10 vib nas this.
2. Kev sib xyaw ntawm cov ntawv dawb thiab cov hlau nplaum: Ntaus lub whiteboard nrog lub zog ntawm 1KG kom pom tias cov hlau nplaum poob.
3. Crayon: Thaum sau ntawm 45-degree kaum sab xis nrog lub zog tsawg dua 1.5 kg, saib seb puas tawg.
