Isku-xidhka-boodhka Birta Aan-La'aanta ah
Sharaxaada Alaabta
| Magaca Alaabta | Isku-xidhka-boodhka Birta Aan-La'aanta ah |
| Qalab | Waxa laga sameeyay 304 bir ah, boolaladahani waxay leeyihiin iska caabin kiimikaad oo wanaagsan waxaana laga yaabaa inay noqdaan kuwo bir ah oo khafiif ah. Waxa kale oo loo yaqaanaa birta A2. |
| Nooca Madaxa | Madaxa Countersunk |
| Nooca wadista | Fasaxa ka gudba |
| Dhererka | Waxaa laga cabbiraa madaxa |
| Codsiga | Xirmooyinka loo yaqaan 'Chipboard Screws' waxay ku habboon yihiin hawlaha dhismaha fudud, sida rakibidda muraayadaha, derbiyada derbiyada, iyo qalabyada kale ee loo baahan yahay qalab adag oo waara, iyo awoodda ay u leeyihiin inay bixiyaan dhufays adag, waxay si ballaaran u adeegsadaan isku dhafka chipboard iyo MDF. (fibreboard cufan dhexdhexaad ah) alaabta guriga. |
| Heerka | Muraayado la kulma ASME ama DIN 7505(A) oo leh halbeegyada cabbirka. |
Faa'iidooyinka ay leeyihiin birta aan fiicnayn ee Chipboard Screws
1. Loogu talagalay in si gaar ah loogu isticmaalo chipboard-ka, boolashan madaxa fidsan ee chipboard-ka ayaa bixiya xajin adag oo ammaan ah, ka hortagaya walxaha inay dillaacaan ama dillaacaan.
2. Biraha looxa baallaha ah way fududahay in lagu dhex wado walxaha, inta badana leh bar fiiqan iyo dun qoto dheer oo ka caawisa in si hufan loo qabsado alwaax.
3. Lagu heli karo tiro balaadhan oo cabbir iyo dherer ah, AYA chipboard screws ayaa la dooran karaa si ay ugu dhigmaan baahiyaha gaarka ah ee mashruuc kasta.
4. Naqshadeynta madaxa countersunk waxay u oggolaaneysaa kuwan boolal-boodhka ah inay ku fadhiistaan dusha sare, iyagoo siinaya dhammaystir nadiif ah oo xirfad leh alaabta la soo ururiyey.
5. Biraha birta ah waxay aad ugu adkaysataa miridhku iyo daxalka, taas oo ka dhigaysa kuwan Screws ee MDF ku habboon in loo isticmaalo jawiga qoyaanka ama xaaladaha cimilada adag.
6. AYA Fasteners waa alaab-qeybiye tayo sare leh oo la isku halayn karo, oo leh nidaamka kaydinta iyo saadka ee qaan-gaadhka ah, iyo aaladaha dhijitaalka ah ayaa ka dhigaya badeecada si hufan ugu socota macaamiisheena.
Isticmaalka biraha aan birta lahayn ee Chipboard Screws
Naqshadihii looxa looxyada waxaa inta badan loo isticmaalaa alwaax-samaynta sida isku-xidhka alaabta guriga ama sagxadaha, iwm. Tani waa sababta aan sidoo kale ugu yeerno boolal loogu talagalay alwaaxyada ama boolal MDF. AYA waxay bixisaa boolal badan oo chipboard ah oo dhererkoodu yahay 10mm ilaa 100mm. Guud ahaan, boolalyada yaryar ee loo yaqaan 'chipboards' waxay ku fiican yihiin in lagu dhejiyo dhejisyada armaajooyinka chipboard-ka halka boolal waaweyn loo isticmaalo in lagu daro qaybaha waaweyn ee golaha, iwm.
Asal ahaan, waxaa jira laba nooc oo boolal ah oo loo yaqaan 'chipboards': zinc-plated white iyo zinc plated huruud ah. Dajinta zinc kaliya maaha lakabka ilaalinta si looga hortago daxalka laakiin sidoo kale waa mid u dhigma bilicda mashruuca. Waxaa loo qaabeeyey iyadoo leh madax countersunk (sida badan madax labajibbaaran), shank caato ah oo leh dun aad u qallafsan, iyo barta is-taajinta.
Talooyinka ugu muhiimsan ee boolal chipboard ee codsiyada waa kuwan soo socda:
1. furka MDF waa in lagu kaxeeyaa in ka badan inch cidhifka alaabta.
2. Xirmooyinka chipboard-ka waa in lagu dhex ridaa wax ka badan 2.5 inji dhammaadka.
3. Adkeynta xad-dhaafka ah waa in laga fogaadaa sababtoo ah waxay wiiqi kartaa haynta looxa.
