Amabara ya zinc yashizwemo amabara: guhanga udushya? 

Urabona 'amabara ya zinc yometseho amabati' kurupapuro rwihariye cyangwa kurubuga rwabatanga isoko, kandi reaction ihita mumasoko menshi cyangwa ibigo byubwubatsi ni ugushidikanya. Nibintu byo kwamamaza gusa? Nuburyo bwo kwishyuza premium yihuta isanzwe ifite irangi rito mubwogero? Nabaye muburyo bwihuse bwo gushakisha no gusaba igihe kirekire kugirango dusangire ubwo bwicanyi. Gusimbuka kubibona nkuburanga bwiza kugirango tumenye ko bishoboka, nubwo byoroheje, Guhanga udushya bisaba gucukumbura mubikorwa nyirizina, kunanirwa, hamwe nukuri-kwisi-kugurisha ibicuruzwa impapuro zitigeze zikubwira.

Igitekerezo kitari cyo: Ni irangi gusa

Inzitizi nini ni ugutekereza ko ibara ari ikote hejuru, nk'irangi rya spray. Ibyo byaba ari ibyago byo kurwanya ruswa no kwihanganira insanganyamatsiko. Inzira tuvuga ni Gutanga amabara ya zinc, byumwihariko nyuma yo gushiraho isahani ya chromate ihinduranya aho amarangi ahujwe. Bolt ibona urwego rwa zinc rusanzwe rwo kurinda ibitambo, hanyuma ikoga imiti ya passivation. Muri ubu bwogero niho umunyu wibyuma ukora urwego rugoye, kandi amarangi kama arashobora kwinjizwa muri iyo matrise. Ibara ntabwo ryicaye hejuru; ni igice cya ruswa-ibuza urwego rwonyine.

Ndibuka umushinga wimyaka yashize kumashanyarazi yo hanze. Umwubatsi yashakaga ko umukara wirabura uhuza imiterere, kandi itsinda ryo kubungabunga ryatsimbaraye kuri galvanised kugirango ruswa. Rwiyemezamirimo, agerageza guta igihe, yakoresheje ibisanzwe bisanzwe kandi asiga irangi umukara kurubuga. Mugihe cyamezi 18, twagize guhamagarwa kubifata. Irangi ryaciwe mugushiraho, ritera micro-icyuho, ubushuhe bwageze munsi, kandi zinc ntishobora gukora akazi kayo neza. Byari ibintu bisanzwe byo gukemura amabara inzira itari yo, gutesha agaciro ibikorwa byibanze.

Aho niho inzira ya zinc ikwiye yerekana agaciro kayo ka mbere ifatika: ihuza amabara ya code cyangwa ubwiza bujyanye no kubungabunga, ndetse rimwe na rimwe ndetse byongerewe imbaraga, imikorere ya ruswa. Igice cya chromate, cyaba gisobanutse, umuhondo, umukara, cyangwa icyatsi, kongeramo inzitizi yinyongera. Guhanga udushya rero ntabwo ari ibara kuri buri; ni kwishyira hamwe nta guhuzagurika gukora.

Inguni irambye: Birenze Guhura Ijisho

Iyo tuvuze kuramba mugufunga, mubisanzwe byerekeranye nibikoresho (ibyuma bisubirwamo) cyangwa uburyo bwo gutwikira (kugabanya chromium hexavalent). Uwiteka amabara ya zinc Inguni ni subtler. Tekereza ku micungire yumutungo muruganda runini cyangwa uruganda rukora. Ufite ibirometero byinshi byo kuvoma, sisitemu zitandukanye (amazi, gaze, imirongo yimiti), byose bifatanyirizwa hamwe nibihumbi. Niba buri bolt ari silver zinc, kumenyekanisha kubungabunga, kugenzura, cyangwa gusimburwa ninzozi mbi. Wishingikirije kuri tagi yazimye cyangwa kwibuka.

Noneho, vuga ubururu bwubururu kumirongo yamazi meza, umutuku kumuvuduko ukabije wicyatsi, icyatsi kubirindiro byumutekano. Mu buryo butunguranye, imiyoborere igaragara ni imbere. Ibi bigabanya amakosa mugihe cyo gusana. Umutekinisiye ntazabura gukuraho impanuka ikomeye ya bolt yibwira ko ari iyumuyoboro udakenewe. Ibi byongera ubuzima bwumutungo, birinda abasimbura bitari ngombwa, kandi bigabanya gukuraho-no guta. Ibyo ni ibintu bifatika, nubwo akenshi birengagizwa, inyungu zirambye-kugabanya imyanda binyuze mu kuramba no kwizerwa.

Hariho kandi ikibazo cya chromium ya hexavalent. Kurangiza gakondo yumuhondo zinc kurangiza akenshi ikoresha chromate ya hexavalent, igenzurwa cyane (RoHS, REACH). Inzira yamabara, cyane cyane umukara nigicucu cyijimye, akenshi ikoresha ubundi buryo bwa chromate butandukanye kugirango ugere kumurongo. Chrome ntoya ntago ari uburozi kandi bwangiza ibidukikije. Rero, kwerekana ibara birashobora rimwe na rimwe kuba inzira yo kutarwanya kwimura umushinga werekeza ku bidukikije byangiza ibidukikije nta kurwana kubyerekeranye nibikorwa.

Hiccups zifatika no gutanga urunigi rwukuri

Ntabwo byose byoroshye. Guhoraho ni inyamaswa. Kubona igicucu kimwe cyubururu kuva mubice kugeza mucyiciro, cyangwa no mubice bimwe, biragoye. Kwinjiza irangi biterwa niminota itandukanye muri chimie ya passivation yo koga, ubushyuhe, nigihe. Nagize ibyoherejwe aho itandukaniro ryamabara ryagaragaye bihagije kuburyo umwubatsi yabyanze kugirango porogaramu igaragara. Tugomba kurya ikiguzi. Kubikorwa byinshi byinganda, guhindura gato hue ntaho bihuriye, ariko ugomba kumenya kwihanganira gusaba kwawe kubitandukanye.

Indi hiccup ni ukurwanya kwambara. Igice cya chromate gifite irangi kirashobora kuba gike cyane-idashobora kwihanganira kurenza ibice binini, bisobanutse. Mugihe cyo kwishyiriraho ibikoresho byingufu cyangwa niba bolt ikururwa binyuze mumurongo wibyuma, urashobora kubona ibimenyetso byoroheje byerekana zinc munsi. Ni kwisiga gusa kandi ntabwo bigira ingaruka kuri ruswa, ariko ni ingingo yo gutongana nabakiriya ba finike. Wiga kwerekana intoki-guterana inteko ya nyuma cyangwa gukoresha ibikoresho byo gukingira ahantu hagaragara.

Aha niho gukorana nu ruganda kabuhariwe bigira icyo bihindura. Isosiyete nka Hamagara zitai yihuta ukora co., Ltd., ishingiye mu Bushinwa bunini bushingiye ku bicuruzwa bisanzwe muri Yongnian, ifite ingano nuburyo bugenzura gucunga izo mpinduka neza kuruta iduka rito ryakazi. Aho biherereye hafi yinzira nini zitwara abagenzi nka Gari ya moshi ya Beijing-Guangzhou na Express ya Beijing-Shenzhen ntabwo ari ukwirata gusa; bivuze ko bagenewe ibintu bihoraho, binini binini bisohora imikorere yimiti. Urashobora kubona uburyo bwabo kurangiza bwihariye nkibi kurubuga rwabo https://www.zitaifacens.com. Ntabwo bakora ibihindizo gusa; barimo gucunga ubwogero bwa chimie kurwego rwinganda, nicyo ukeneye kugirango uhuze amabara.

Urubanza mu ngingo: Ikigeragezo cyatsinzwe nitsinzi

Twigeze kugerageza gukoresha umukara wa zinc ushyizweho na sisitemu ya gari ya moshi yo ku nkombe. Icyifuzo cyasabye kurangiza umwijima no kurwanya ruswa. Twabonye icyitegererezo cyiza, kimwe. Ariko mu bizamini byo gutera umunyu (ASTM B117), igifuniko cyirabura cyerekanaga ibicuruzwa byangirika byera (umunyu wa zinc) bigaragara cyane kandi byihuse kuruta mugenzi we usanzwe wumuhondo. Imikorere ya ruswa, ukurikije imibare, yarasa, ariko kunanirwa kugaragara byihuse. Umukiriya yagize ubwoba ku mafoto, yibwira ko igifuniko cyatsinzwe rwose. Twize ko kubidukikije byangirika cyane, bigaragara cyane ibidukikije, kwangirika kwubwiza bwimyambaro yamabara bigomba kuba mubice byo gusuzuma, ntabwo ari iherezo ryumutuku. Rimwe na rimwe, kutagaragara neza gutwikiriye ni amahitamo meza.

Gereranya ibyo hamwe nubutsinzi mubwubatsi bwimbere. Isosiyete yubaka ibyumba byibitaro bya prefab yakoresheje ibara ryanditseho amabara: orange kumashanyarazi yumuyagankuba, ubururu kumirongo ya gazi yubuvuzi, imvi kumurongo wububiko. Bose bari ZINC-COLTS hamwe nibara rya chromate. Mugihe cyo guhimba hanze, abakozi bashoboraga kugenzura byihuse ko bafata icyuma gikwiye kugirango kibe cyiza. Ku rubuga, abagenzuzi bashoboraga kugenzura sisitemu iyo urebye. Igiciro cyambere cyambere cyarangijwe no kugabanya amakosa yo guterana no kwishyiriraho byihuse. Intsinzi irambye yari mukugabanya imirimo, imyanda mike ivuye mubikorwa bitari byo, kandi byoroshye guhinduka ejo hazaza kuko sisitemu yashushanyije.

None, Mubyukuri ni agashya?

Kubyita ibintu bishya, bihindura isi bishya byaba birenze urugero. Nukwiyongera, gusaba-gutunganywa. Uwiteka Guhanga udushya ikirango gihuye mugihe usuzumye ubuzima bwose: ubushobozi bwo gukoresha chromates nkeya zifite uburozi, kugabanya imyanda binyuze muburyo bunoze bwo kumenyekanisha no kuyitaho, hamwe nubuzima bwa serivisi bwagutse ukareba ko kwihuta gukoreshwa bikoreshwa mubidukikije neza uhereye mugitangira.

Ntabwo ari kuri buri porogaramu. Kubice byinshi byiziritse byashyinguwe mumashini cyangwa imiterere, nigiciro kidakenewe. Ariko aho ibara ryongera imikorere-umutekano, kumenyekanisha, gucunga sisitemu-irenze imitako. Ihinduka igikoresho cyo gukora neza no kuramba.

Urufunguzo rwa ba injeniyeri nababisobanura ni ukunyura hejuru kuki nashaka ibara ryamabara? imitekerereze yo kubaza irashobora gukemura ibara ryihishe cyangwa ibyago muriyi nteko? Ngiyo guhinduka. Nigice gito, ariko nkuko umuntu wese mubikorwa abizi, satani, kandi rimwe na rimwe agakiza, biri muburyo burambuye. Tekinoroji, kimwe niyubahwa nabaproducer muri hub nka Yongnian, irakuze. Agashya kari mubitekerezo byacu kuburyo twakoresha.
