Inyigisho y'ingenzi ku muguzi: Uburyo bwo guhitamo isahani y'ubuso bwa granite hakurikijwe amahame ya DIN, ASME, na JIS

Isahani y'ubuso bwa granite ni ishingiro ry'ibipimo by'ingano. Ni yo ngero y'ibanze aho ibipimo byose bigereranywa. Ariko si amasahani yose y'ubuso agereranywa—kandi si ko amahame yose ari amwe. Niba urimo gushyiraho isahani y'ubuso ya laboratwari y'ibipimo, ishami ry'ubugenzuzi, cyangwa ikigo cyo gupima, gusobanukirwa itandukaniro riri hagati y'amahame ya DIN, ASME, na JIS si iby'ubumenyi gusa. Ni itandukaniro riri hagati yo kugura isahani yujuje ibisabwa byawe no kugura itayiguze.

Imiterere y'Ibipimo ngenderwaho

Amabwiriza mpuzamahanga menshi agenga uburyo bwo gukora neza no gupima amasahani y'ubuso bwa granite. Akoreshwa cyane arimo:

• DIN 876 (Igipimo ngenderwaho cy'Abadage), gitwikira ibyuma bitwikiriye ubuso kugira ngo bigenzurwe kandi bipimwe
• ASME B89.3.7 (ibipimo ngenderwaho by'Abanyamerika), byasimbuye ibyahoze ari ibya Federal Specification GGG-P-463C

• JIS B 7513 (Igipimo ngenderwaho cy'Abayapani), gitwikira ibyuma bipima neza
• GB/T 20428 (Igipimo ngenderwaho cy'Abashinwa)
• BS 817 (Igipimo ngenderwaho cy'Ubwongereza)

Buri gipimo gisobanura amanota atandukanye yo gukora neza, uburyo bwo gupima, n'ibipimo byo kwemerwa. Icyapa cyujuje DIN 876 Grade 00 gishobora kutujuje ASME B89.3.7 Grade AA—n'ibindi.

Gusobanukirwa amanota y'ubunyangamugayo

Ubuhanga bw'isahani y'ubuso bwa granite bukunze kugaragazwa mu buryo bwo kwihanganira ubugari bw'isahani ku buso ikoraho. Dore igereranya rusange:

L = uburebure bw'icyuma gipima uburebure muri mm

Ikintu cy'ingenzi: isahani iriho "Impamyabumenyi ya 00″ munsi ya DIN ntabwo ari ngombwa ko ingana na "Impamyabumenyi ya AA" munsi ya ASME. Uburyo bwo gupima buratandukanye, amanota yo gupima aratandukanye, kandi ibipimo byo kwemerwa biratandukanye.

Icyo wakwitaho mu isafuriya nziza

Uretse urwego rw'ubuziranenge, hari ibintu byinshi bigaragaza niba plaque yo hejuru izakora uko iteganijwe mu gihe cyose ikora:

Ubwiza bw'ibikoresho. Granite igomba kuba ifite ibice bito, idafite inenge, kandi ifite ubucucike bumwe. Granite yujuje ubuziranenge ishobora kuba irimo uduce duto dutuma idahungabana igihe kirekire. Muri ZHHIMG®, dukoresha granite y'umukara ya ZHHIMG® ifite ubucucike bwa ≈3100 kg/m³—iruta granite nyinshi z'umukara zo mu Burayi no muri Amerika—bituma ikomera kandi idashira.

Ubukomere n'Ubudahangarwa. Isahani yo hejuru igomba kwirinda gushwara no kwangirika bitewe no gukoreshwa kenshi. Granite yacu ifite ubukomere bwa Mohs buri hagati ya 6 na 7, ikaba itanga ubudahangarwa bwiza bwo kwangirika mu myaka myinshi ikoreshwa buri munsi.

Ubushyuhe buhamye. CTE y'ibuye rya granite igomba kuba iri hasi kandi ishobora gusobanurwa uko bishoboka kose. Ibuye ryacu ry'umukara rya ZHHIMG® ritanga ubushyuhe buhamye cyane, rigakomeza kuba rirerire mu bushyuhe butandukanye butuma ibyuma bihindagurika.

Gupima no Gukurikirana. Icyapa kigomba kuba kirimo icyemezo cyo gupima gikurikirana ibipimo by’ikigo cy’igihugu gishinzwe gupima. Muri ZHHIMG®, buri cyapa cy’ubuso gipimwa hakoreshejwe ibikoresho byemejwe n’Ikigo cya Jinan gishinzwe gupima n’Ikigo cya Shandong gishinzwe gupima, hamwe n’icy’Ikigo cy’Igihugu gishinzwe gupima n’Ubushinwa.

Uruhare rw'ubukorikori bw'ubuhanga

Ndetse na granite nziza cyane ntacyo imaze iyo itarangijwe neza.isahani yo hejuru ya graniteIrimo ibice bibiri by'ingenzi: gutegura ubusa no gutunganya neza. Ubusa bucibwa neza uhereye ku gice cyacukuwe, hanyuma bugasigwa neza kugeza ku buryo bungana. Ariko intambwe ya nyuma—kugeza ku rwego rwagenwe rw'ubusa—isaba ubuhanga mu gukanda intoki.

Abatekinisiye b'abahanga bahindura neza ubuso bw'isahani kugira ngo bagere ku buryo bukwiye kandi bunoze. Buri gice kigomba gukora igenzura rikomeye kugira ngo cyemeze ko cyujuje ibisabwa. Muri ZHHIMG®, imashini zacu zikora ibyuma bisya zifite uburambe bw'imyaka irenga 30 mu gukoresha intoki, zigagera ku buryo bungana na mikorometero binyuze mu buryo bworoshye bwo gukoraho budashobora gukopwa n'imashini.

Inama z'ingirakamaro ku baguzi

Mu kugereranya ibiciro by'inganda zitandukanye, ntukishingikirize ku izina ry'ibikoresho gusa. Saba:

1. Ubucucike nyakuri bwa granite (si "granite" gusa ahubwo n'ubwoko bwihariye n'ubucucike)
2. CTE (coefficient of thermal expansion) ipimwa kuri 20°C
3. Ubushobozi bwo kwihanganira ubugari bwagezweho n'urugero rupimirwamo
4. Icyemezo cyo gupima no gukurikirana amakuru
5. Politiki y'ingwate y'ubuzima bwa serivisi n'iy'ivugurura ry'isura

Niba umucuruzi adashobora gutanga ibi bisobanuro, ibyo ni ikimenyetso cy’umutuku. Inganda nyinshi nto zikoresha marble ihendutse aho gukoresha granite nyayo—uburyo bwo kubeshya turabwamagana cyane. Marble ni yoroshye, ntihindagurika cyane, kandi ikunda kwangirika kurusha granite ikwiye. Itandukaniro si rito; ni itandukaniro riri hagati y’isahani yo hejuru igumana ubuziranenge bwayo mu myaka ibarirwa muri za mirongo n’indi igenda ihinduka mu myaka myinshi.

Kubungabunga no Gusubiza Ibikoresho mu Ivugurura

Isahani yo hejuru ya granite si ishoramari ryo "gushyiraho hanyuma wibagirwe". Ndetse n'isahani nziza cyane zisaba kongera gushyirwaho buri gihe kugira ngo zimenye neza ko zitarava mu bwihangane. ASME B89.3.7 ikubiyemo icyemezo gishya, kongera gushyirwaho mu rwego, no kongera gushyirwaho nyuma yo kongera gushyirwaho. DIN 876 na JIS B 7513 bifite ingingo nk'izo.

Gusukura buri gihe—gukoresha imiti isukura ikwiye, kurinda ubuso kugongwa n’ibintu, no gukoresha ibipfundikizo bikwiye igihe bidakoreshwa—bituma isahani yo hejuru iramba cyane. Kandi iyo isahani ishaje cyane ku buryo yashoboraga kwihanganira, kongera kuyisubiza mu buryo bushya hakoreshejwe umuhanga mu by’ubuhanga bishobora kuyisubiza mu buryo bushya.

Muri ZHHIMG®, ntidukora gusa amasafuriya yo hejuru. Dutanga ubufasha bwuzuye ku buzima—kuva ku bipimo bya mbere no gupima binyuze mu kongera gushyiramo no kongera gushyiramo—kuko twumva ko isafuriya yo hejuru atari igikoresho gusa. Ni wo musingi w'uburyo bwose bwo gupima.
